OH NOOOOO! No riddle!!!!! No time for fun!
Anja is running late to go on holiday – so many things to do and so little time to find a new riddle! Booh!
Maybe next month again! Send one through if you have one on file: 😉
But here’s the solution of last month’s riddle (http://blogs.exeter.ac.uk/xm2news/riddle-time-4/) for you:

Joseph Beadle is taking on the role as Student Advisory Group (SAG) representative for the 2015 cohort alongside Ben Hogan with immediate effect. Joe is taking over from Henry Fernández who contributed actively to the development of the programme on behalf of his cohort since 2016. Henry is stepping down from this role to prioritise his research and the work as president of the Exeter University Optics & Photonics Society (EUOPS).
We would like to thank Henry for his work as SAG member over the past couple of years – and send a very warm welcome to Joe.
SAG consists of normally 2 members of each cohort who represent the student body at meetings with the Management and Oversight Boards. They help to implement new ideas that benefit the overall experience of their peers, to offer different perspectives, and to ensure the PGRs’ opinions are heard. SAG is currently chaired by Ben Hogan.
Please see all SAG representatives and other XM2 PGR ambassadors under http://emps.exeter.ac.uk/metamaterials/about/studentambassadors/
On 16 May 2018 the world saw the celebration of the first ever International Day of Light. The event was celebrated around the world with more than 500 events taking place in 87 countries to create awareness of the role of light plays in science, culture and art, education, and sustainable development, and in fields as diverse as medicine, communications, and energy.
The International Day of Light is a global initiative that provides an annual focal point for the continued appreciation of light in all forms and shapes and applications. It will be held on May 16th every year, the anniversary of the first successful operation of the laser in 1960 by physicist and engineer, Theodore Maiman.
The Optics and Photonics Society of the University of Exeter (EUOPS) did not wanted to miss this opportunity to join the worldwide celebration and organised events open to the entire community of Exeter. They held a photo competition with three main categories, which encouraged participants to showcase how important light is nature, in their day-to-day life and in technology. Bill Barnes, Professor of Photonics at the University of Exeter, had the difficult task to choose the winners among the 57 photo submissions:
Alongside the photo competition, there was a poster competition where the participants were asked to explain to the general public how they use light in their research. There was one simple rule: explain your research in the easiest way possible. The 5 poster submissions were judged by year 12 students (Adam Barber, Peter Betts, Harry Price) and their teacher Dr Aude Alapini-Odunlade from Clyst Vale Community College.
Between these two competitions, £300 in prizes were shared between firsts, seconds, and audience favourite prizes,. The award ceremony was held in the Forum of the University of Exeteron 11th of May.
A very special thanks goes to EUOPS and the XM² 4th year PGR Erick Burgos Parra who organised an outstanding first celebration of the International Day of Light!
Photo competition winners in order of appearance in the text above:
Congratulations to Illia Starshinov and our first XM² graduate Dr Alba Paniagua for their recent Physical Review X article on Non-Gaussian Correlations between Reflected and Transmitted Intensity Patterns Emerging from Opaque Disordered Media, collaborative work between the University of Exeter and The Institut Langevin, Paris.
Summary
Congratulations to Liam Trimby who won the poster prize for his work on “Tunable Band-Pass Filters using Phase-Change Metamaterials” at the 2nd International Symposium on Doped Amorphous Chalcogenides and Devices in the Lake District.
The work demonstrates how phase-change materials can be used in conjunction with periodic hole arrays to manipulate the extraordinary optical transmission phenomenon to create ultra-thin, high performance, tunable band-pass filters. These filters are applied to the role of multispectral imaging and biological sensing.
Very many congratulations to Tanveer Ahmad Tabish who successfully defended his PhD in May 2018. His thesis is titled “DEVELOPMENT OF GRAPHENE NANOSTRUCTURES FOR USE IN ANTI-CANCER NANOMEDICINE”, and has been supervised by Shaowei Zhang and Yongde Xia.
Tanveer will soon be starting a 3-year post-doc position on the £5.7m EPSRC programme grant “Raman Nanotheranostics (RaNT) – developing the targeted diagnostics and therapeutics of the future by combining light and functionalised nanoparticles” led by Prof. Nick Stone. The project will focus on the investigation of nanotheranostic approaches for diagnosis and treatment of cancer.

Congratulations again to Tanveer, and all involved in his success!
Four PGR students from Exeter’s CDT in Metamaterials travelled to Strasbourg to present their work at SPIE Europe, the only cross-disciplinary optics and photonics event in Europe.
The conference covers topics across the most significant photonics technologies—from digital optics to quantum technologies to attosecond science. 2018 saw the addition of 7 new conference topics being covered at the conference, including Advances in Ultrafast Condensed Phase Physics, Unconventional Optical Imaging, 3D Printed Optics and Silicon Photonics.
Our PGRs Alba Paniagua Diaz (“Enhanced deep detection of light for Raman spectroscopy by wavefront shaping“) and Illia Starshynov gave talks on their respective work, and Kieran Walsh (“Wafer scale FeCl3 intercalated graphene electrodes for photovoltaic applications“) and Iago Rodriguez Diez (“Visible Light Emitting Waveguide on Silicon Chip, based on Polymeric Quantum Dots”) presented posters of their most recent research.
Congratulations to Joaquin Faneca and the co-authors who just published the article “One-Dimensional Multi-Channel Photonic Crystal Resonators Based on Silicon-On-Insulator With High Quality Factor” in Frontiers in Physics.
Abstract
We have theoretically and experimentally demonstrated a Fabry-Pérot (FP) resonators based on a Si-air one-dimensional photonic crystal (1D PhC) with coupled triple-cavity modes (or defects). These defects are obtained by filling selected air channels in the 1D PhC with an actively reconfigurable fluid. Simulations of the optical properties of these FP resonators were performed in the wide infrared spectral range. It is shown that by changing the refractive index, nc, of the fluid simultaneously in all three channels, a set of narrow triple resonance peaks can be obtained within wide stop-bands of different order in the infrared range. In addition, at certain values of nc, splitting of the triple resonance peaks into a doublet and a single peak with a significantly larger quality factor, Q = 21,200, occurs. Prototype devices based on Silicon-On-Insulator platform were fabricated and characterized by electro-optical and spectroscopic measurements. The electro-optical measurements demonstrate the possibility of refractive index manipulation of the filler in the FP channels individually or simultaneously. Spectroscopic measurements performed in the range 1540–1630 nm using fiber-coupling confirm the presence of triple resonance peaks in the 3rd stop-band in the absence of an electric field applied to the FP channels. At an applied voltage of 10 V to the middle channel, an increase of Q to 3720 in the single peak is registered.

£15,000 were recently awarded by the ChAMP / WAFT Collaboration Fund to the Physical Chemistry group at Cambridge and researchers at the University at Exeter.
The CDT in Metamaterials PGR Liam Trimby contributed significantly to the development of this proposal, following an idea from Dr A Alexeev to demonstrate a novel approach for chemical sensing based on phase-change IR metamaterial devices, and to use the preliminary results to submit a larger collaborative grant application.
Both the ChAMP and WAFT research projects are funded by EPSRC and work with a number of academic and industrial partners. Synergies between the projects have developed joint funding of PhD student/post-doc led proposals for collaborative research across ChAMP and WAFT.
This project will last from 1-June-2018 to 30-September-2018 and bring together a team from Engineering at the University of Exeter
and a team from Physical Chemistry at the University of Cambridge
Congratulations to the succesful applicants!
