Researchers from Southampton and Bordeaux have unveiled a new technique for the industrial testing of photonics chips, an important step in the realisation of an emerging multi-billion pound industry.
The international research, presented this month in the Nature Communications journal, brings together advanced theoretical modelling and precise experimental studies to develop a quantitative understanding of how light travels through a chip.
Photonic integrated circuits, the technology of using light on a chip, is a rapidly developing industry with applications in data communication and optical interconnects.
Whereas electronic testing of circuits is a mature field, capabilities are still lacking for photonic circuits and not well-suited to industrial-scale testing. There is therefore a strong need to develop advanced probes capable of testing fabricated devices remotely and with high throughput.
Researchers from the Department of Physics and Astronomy at the University of Southampton and the Laboratory for Photonics, Numerics and Nanosciences (LP2N) in Bordeaux, France, have demonstrated the new technique which uses a pulsed laser to divert and then measure the flow of light through a device.
The theory used to interpret these results applies to many photonic systems with great accuracy and minimal computational cost. Comparisons between the experimentally obtained and modelled maps for the devices showed agreement as high as 95%, a clear indication of the robustness of the model and of the experimental technique.
Professor Otto Muskens,, from Southamptonâs Integrated Nanophotonics Group and Principal Investigator of the study, says: "Our new technique will be of interest for photonics industry and we are actively looking for end users to test our methods in real-world applications. Further development will be needed to explore the integration of the technique into actual probe stations used by industry, ultimately merging optical and electronic testing onto one single platform.â?
The work was supported by the UK Silicon Photonics for Future Systems research programme and involved Southamptonâs state-of-the-art cleanroom facilities and the Silicon Photonics research group led by Professor Graham Reed.

Andreas Jüttner is an Professor of Theoretical Physics in the Southampton High Energy Physics Group. After graduating from Friedrich-Alexander Universität Erlangen-Nürnberg he did a PhD in Computational Particle Physics at the Humboldt Universität zu Berlin. After his time as a post doc in Southampton and Mainz (Germany) he spent time at CERN in Geneva, Switzerland, as a CERN Fellow in the Theory Department. He returned to Southampton on an European Research Council Starting Grant in 2012. Andreas is currently on leave of absence on a staff position in the CERN Theory Department.
Until 05/2021 Andreas was director of the EPSRC Centre for Doctoral Training "Next Generation Computational Modelling". He is founding member of the Flavour Lattice Averaging Group (FLAG) where he is currently on the Editorial Board.
Research
Research interests
Andreas' research focuses on understanding the fundamental constituents of matter. He is particularly interested in the theory of strong interactions that describes how quarks and gluons interact to form mesons and baryons (e.g. protons, which make up the visible matter surrounding us). His research addresses the many unresolved questions still remaining such as why there is more matter than anti-matter in the universe and how the universe began. His results help understanding experimental findings coming in from the experimental facilities at e.g. the LHC at CERN in Switzerland (e.g.LHCb), KEK in Japan (BelleII), Fermilabin the US (g-2) and J-PARC in Japan (g-2).
Andreas is also interested in the development and improvement of simulations algorithms and in applying lattice techniques in other research areas. The aspects of the strong interaction Andreas is most interest in can be understood by means of numerical simulations, solving the equations of motion on high performance computers (Lattice Quantum Field Theory). To this end he is PI for a large computing time grant on DiRAC's super computers and he is also using computing resources for instance in the US or Southampton's Iridis compute cluster. He is member of the RBC/UKQCD collaboration and he is collaborating with researchers from Edinburgh, the US (Columbia University, Brookhaven National lab), Germany, Denmark and Japan (KEK).
More recently Andreas is using his expertise to address questions in Holographic Cosmology and Machine Learning.

Staff in Physics and Astronomy at the University of Southampton are constantly shaping the subjectâs education and research environment by publishing findings and expressing expert opinion. Hereâs a round-up of some of our most recent achievements:
Supersymmetry Beyond Minimality
Southamptonâs Professor Stefano Moretti and Professor Shaaban Khalil, General Director of Research at Zewail City of Science and Technology, Egypt, have published Supersymmetry Beyond Minimality: From Theory to Experiment. This graduate textbook and researcher reference guide to supersymmetry, an extension of the Standard Model of Particle Physics, includes the latest results from data analyses of the Large Hadron Collider (LHC).
Cosmology and the Early Universe
Professor Pasquale Di Bari explores cosmology, the study of the origin and evolution of the universe, in his new book Cosmology and the Early Universe. This undergraduate textbook contains a discussion of modern cosmology results, including the detection of gravitational waves which was recognised by the Nobel Prize for Physics in 2017.
Theories of Matter, Space and Time
Professor Nick Evans and Professor Steve King from the Southampton High Energy Physics (SHEP) Group have co-authored Theories of Matter, Space and Time, Volume 1, an undergraduate guide through topics covered in the third and fourth year of courses at Southampton. The book offers sophisticated views of classical mechanics, special relativity, electromagnetism and quantum theory and addresses their interdependence.
Understanding Nothing
Professor Nick Evans has also released short read Understanding Nothing this spring, a written version of a popular talk covering early ideas of the vacuum, Newtonian gravity, relativity and quantum theory, leading up to the discovery of the Higgs boson and the outstanding problem of a full quantum theory of gravity.

Physicists from the University of Southampton have used simulations on high performance computers to determine the properties of a fundamental particle with unprecedented precision.
Comparisons of the super computer calculation with data from international experiments could either confirm or challenge the Standard Model of Particle Physics, a long-established theory for fundamental particles and how they interact.
Researchers in the Southampton High Energy Physics (SHEP) theory group are working with international partners to predict the effects of magnetic fields on muons, an unstable subatomic particle with properties similar to an electron. Their calculation of the hadronic vacuum polarisation contribution to the muon anomalous magnetic moment is part of a Standard Model prediction that will be compared to the results of experiments taking place in the USA and Japan.
The groupâs research paper has been accepted for publication in the prestigious journal Physical Review Letters and selected for the âEditorsâ Suggestionâ, which highlights papers that are âparticularly important, interesting and well writtenâ?.
Dr Andreas Jüttner, a Principal Research Fellow in Physics and Astronomy, explains, âOver the last few decades physicists have developed a comprehensive understanding of theoretical physics, crowned by the discovery of the Higgs boson in 2012 and leading to the award of the 2013 Nobel Prize in Physics to Englert and Higgs. There is a lot of other evidence however that our current understanding is not the full picture of nature. Indeed, known matter only makes a few percent of the nature of the universe, so there is a lot left to explain.
âOur strategy has been to make precise theoretical predictions and confront them with precise experimental measurements. Itâs really exciting since we managed to make our prediction before the experiment publishes new data early in 2019.â?
The Southampton research team involved in the project received support from Andreasâ European Research Council Starting Grant and included postdoctoral researchers Dr Vera Gülpers, Dr Antonin Portelli and Dr Justus Tobias Tsang. They are working with partners at the University of Edinburgh, Columbia University, Brookhaven National Lab and the University of Connecticut.
The research has used a method called Lattice Quantum Chromodynamics (Lattice QCD). Its calculation is performed by constructing a discrete four-dimensional space-time grid, known as the lattice, to numerically solve the QCD equations of motion. Such lattice QCD simulations are the only known method to address certain questions without having to rely on ad hoc assumptions.
This type of computation crucially relies on access to the worldâs fastest parallel supercomputers and this research has benefited from a computing time grant from DiRAC, Distributed Research utilising Advanced Computing.
Andreas adds, âWe are looking forward to finding out whether the Standard Model of Particle Physics will be confirmed by experiments taking place this year, but if they disagree it will be the strongest possible indication that we have found new physics.â?

Physics rose six places to be ranked sixth in the guide, with a 99.0 out of 100 score positioning it second in the country â and first in the Russell Group â for satisfaction with the course.
The Guardian University Guide ranks 121 UK institutions and focuses on undergraduate study and experience. Rankings are based around criteria of entry tariffs, student satisfaction, graduate prospects, student-staff ratio and university spend per student.
Professor Jonathan Flynn, Head of Physics and Astronomy, says: âWe are thrilled to be sixth in the Guardian league table for Physics, and first in the Russell Group for overall student satisfaction. The Guardian University Guide emphasises the students' perspective and we think our top 10 position reflects the effort we make to support our students. We will not be complacent, however, and will continue to work to improve our students' experience and their future prospects.â?
Physics and Astronomy is joined in the top 10 by other subjects in the Faculty of Physical Sciences and Engineering; Computer Science and Information Systems is ranked 8th and Electrical and Electronic Engineering (EEE) is 2nd .
Professor Bashir Al-Hashimi, Dean of Physical Sciences and Engineering, adds: âEEE is consistently ranked among the best departments in the UK and this outstanding result reinforces that the University and Electronics and Computer Science provide educational experience and training of the highest quality to our students. I am also delighted that Computer Science and Physics are among the top 10 in their disciplines, which is a fantastic achievement. Such consistent results are testament to the expertise and commitment of our staff as well as the leadership at a Department and Faculty level.â?
The University of Southampton rose 12 places to be ranked 23rd overall in the 2019 guide. The improvement comes a month after the Universityâs return to the top 20 in the 2019 Complete University Guide.

Astronomer Liz Bartlett and a team at the European Southern Observatory (ESO) have located a concealed neutron star in a much-studied supernova remnant.
Their research, published recently in Nature Astronomy, represents the first discovery of an isolated neutron star with a low magnetic field beyond our galaxy.
The finding was driven by new data from the Multi Unit Spectroscopic Explorer (MUSE) instrument on ESOâs Very Large Telescope in Chile, which highlighted a donut-shaped cloud of gas in the supernova remnant, known as known as 1E0102.2-7219, located 200,000 light years away in the Small Magellanic Cloud galaxy. The location of the stellar corpse was then verified by examining existing observations from NASAâs Chandra X-ray Observatory, which Liz has worked with since the year abroad programme during her undergraduate study in Southampton.
âWhilst there are many supernova remnants out there, it can be very difficult to find what remains of the exploded star; the neutron star or black hole. They are intrinsically very faint and buried in supernova material,â? Liz explains. âKnowing the current location and properties of the central compact object gives us more clues as to the dynamics of the explosion and the nature of the progenitor star, which in turn can further our understanding of stellar evolution as a whole.â?
âWith MUSE we identified a peculiar ring of light: a gas cloud expanding slowly within the depths of numerous other fast-moving filaments of gas and dust,â? Liz adds. âThis had never been seen before now, simply because we didn't have the instrumental capabilities. When we looked at the archival data from Chandra, we saw a faint point source perfectly centred on the ring.â?
Liz completed undergraduate and postgraduate degrees at the University of Southampton before starting an international career that has most recently taken her to ESO in Santiago, Chile. She graduated with an MPhys Physics with Astrophysics with a Year Abroad in 2009 before returning for a PhD which she finished in 2013.
âQuite simply, the year abroad programme is why I am here today,â? she explains. âMy research is still linked to work I did back then. The Chandra X-ray Observatory used for this most recent study is run from the Harvard-Smithsonian Center for Astrophysics (CfA), where the year abroad programme is based. I wouldn't be where I am now without my year at the CfA.â?

Postgraduate researcher Rebecca French has been recognised for her exceptional contribution toward gender equality with a Women in Science, Engineering & Technology (WiSET) Award.
Rebecca has been a driving force behind the University of Southamptonâs influential Womenâs Physics Network as she progresses with research in Physics and Astronomyâs Quantum, Light and Matter group.
She was presented a WiSET Award Trophy and cash prize alongside fellow winner Emma Osborne of Mathematical Sciences in a Highfield Campus ceremony on Wednesday 9th May.
âThere are so many incredible people across the University who work tirelessly to raise the profiles of women in science, technology, engineering, mathematics and medicine (STEMM), not only within our University, but in countries around the world,â? Rebecca says. âI've always been blown away by the achievements of the recipients of past WiSET Awards, and so I feel very humbled to be awarded at the same level as them.â?
Rebecca completed an MPhys Physics degree at Southampton in 2014 and continued in the department with a PhD in compact spectral imaging systems, involving visiting research at the Laboratoire Kastler Brossel in Paris.
âI was surprised to find that women donât have a better representation in physics internationally because it was one of the most popular subjects at my girlsâ school,â? she explains. âI soon became motivated to change the culture in science in order to alter the perception of what a scientist looks like, and to encourage girls and women to study and work in science. Iâm also pleased to say that Southamptonâs Physics and Astronomy department has always been extremely supportive of all of their students, regardless of gender.â?
Rebecca has been a member of the Womenâs Physics Network (WPN) since its first meeting in 2014 and served as a Chair or Co-Chair of the WPN Committee over the past three years. The network organises seminars, talks and outreach events that promote the career development of women and champion gender equality and diversity in the department.
Rebecca has also contributed as the postgraduate representative for Physics and Astronomyâs Equality, Diversity and Inclusion Committee since 2016 and acted as a positive role model by helping deliver public engagement activities like the Universityâs Light Express Roadshow and the WISE Campaign's People Like Me workshop for girls and their mothers.
This month, Physics and Astronomy at Southampton has also been recognised for its commitment to tackling gender inequality with an Athena SWAN Silver Award. The status builds upon Bronze Award status granted in 2015 and reflects a continued drive to improve the life and culture of all people in the department.
