Abstracts
F1 – 8:30 (Keynote)
PCSELs: The 2D Laser Commercialisation Journey, Richard Taylor, Vector Photonics, UK. Photonic crystal surface emitting lasers (PCSELs) are a new class of lasers with advantages over incumbent technologies. Vector Photonics was formed in 2020 to commercialise PCSEL technology. In this talk we review the commercialisation journey.
F2 – 9:00 (Invited)
Recent Developments in Integrated Comb and Tunable Laser Assemblies, Shane Duggan, Pilot Photonics, UK. iTLA are integrated tunable laser assemblies and Pilot Photonics’ offering addresses industry needs of wide tuning, nanosecond switching and narrow linewidth; while our iCLA is an integrated comb replacing 4 iTLAs for efficient capacity expansion.
F3 – 9:20 (Invited)
High-Speed Electro-Optic Modulators, Shiyoshi Yokoyama1,2, Futa Uemura2, Jiaowei Mao1, Hiromu Sato1, and Guo-Wei Lu1, 1Institute for Materials Chemistry and Engineering, Kyushu University, Fukuoka 816-8580, Japan, 2Department of Molecular and Material Science, Kyushu University, Fukuoka 816-8580, Japan. We demonstrate a high-speed MZI modulator that is based on a strong Pockels waveguide stacked on the silicon oxide insulator. The modulator performed >160 Gbaud transmission for both c-band and o-band.
F4 – 9:40 (Contributed)
Laser Metrology and Beam Diagnostic: A New Approach to ISO 11146 Standard, Audrius Jasaitis1, Bérénice Renard1, Rafael Porcar1, Xavier Levecq1, 118, rue Charles de Gaulle, 91400 Orsay, France. M-Squared parameter is frequently used by laser manufacturers and users to test laser quality. Conventional approach is tedious due to alignment and measurement cycle duration. We propose a new approach addressing these issues.
F5 – 10:30 (Invited)
Dynamic Metasurfaces, Sebastian A. Schulz, Laura C. Wynne, Anindita Das, Jianling Xiao and Andrea Di Falco, SUPA, School of Physics and Astronomy, University of St Andrews, UK. Photonic metasurfaces hold great potential for shrinking optical components and devices, as well as creating new functionality. Here we present our recent progress on dynamic metasurfaces that have non-static properties and whose response can be controlled post-fabrication.
F6 – 11:00 (Contributed)
Spectroscopic Evaluation of PEGDM Hydrogels for Osteogenic Progression Monitoring, Imanda Jayawardena, Rekha Gautam and Stefan Andersson-Engels, Tyndall National Institute, Lee Maltings Complex Dyke Parade, Cork, Cork, T12 R5CP, Ireland. To mitigate bone implant failure, PEGDM hydrogels were evaluated for their suitability for osteogenesis with the aid of Raman spectroscopy. Ability to detect hydroxyapatite as a spectral marker in hydrogels was also evaluated via Raman.
F7 – 11:20 (Contributed)
Methane Sensing with Undetected Light, Arthur C. Cardoso, Jinghan Dong, Haichen Zhou, Siddarth K. Joshi and John G. Rarity, Dept. of Electrical and Electronic Engineering, University of Bristol, Merchant Venturers Building, Woodland Road, Bristol BS8 1UB, UK.

Investigation of a Graded Epsilon-Near-Zero Medium in a Plasmonic Metasurface, Anindita Das, Laura C. Wynne, Andrea Di Falco and Sebastian A. Schulz, School of Physics and Astronomy, University of St Andrews, St Andrews KY16 9AJ, UK. Here, we demonstrate that plasmonic dipole nanoantennas on a graded ENZ substrate have optical properties significantly different from antennas on a conventional ENZ substrate. Our hybrid-graded ENZ Metasurface offers an efficient nonlinear optical platform.
P2
Optical Measurements of Oscillating Shock Waves by High-Speed Mach-Zehnder Interferometry with the Finite-Fringe Setting, Takato Inadomi, Shinichiro Nakao and Yoshiaki Miyazato, Department of Mechanical Systems Engineering, The University of Kitakyushu, 1-1 Hibikino, Wakamatsu-ku, Kitakyushu, Fukuoka, 808-0135, Japan. A high-speed Mach-Zehnder interferometry with the finite-fringe setting is used to capture the time-resolved density field of oscillating shock waves that appear in supersonic air flows.
P3
Quantum Communications ATP Systems: Challenges and Next Steps, James J. Shawe, Jerry Horgan and Deirdre Kilbane, Walton Institute, SETU West Campus, Carriganore, X91P20H, Waterford, Ireland. We report on the current state of the art of quantum communications acquisition, tracking and pointing (ATP) systems. Challenges and next steps are explored.

Tilted Fiber Bragg Grating Sensing Platforms: How to Process Their Comb-Like Amplitude Spectrum? Hadrien Fasseaux1, Médéric Loyez1,2, Christophe Caucheteur1, 1Advanced Photonic Sensors Unit, University of Mons, Boulevard Dolez 31, 7000 Mons, Belgium; 2 Proteomics and Microbiology Department, University of Mons, 7000 Mons, Belgium. Tilted fiber Bragg gratings are very sensitive to surrounding refractive index changes, especially when they are surrounded by a thin gold film. We review here the main strategies to demodulate their comb-like transmitted amplitude spectrum.
P5
The Topology of Twisted Fibres, Brook Salter, Nathan Roberts, Anton Souslov and Peter J. Mosley, University of Bath, Claverton Down, Bath, BAS 7AY, UK. We explore methods for designing and analytically characterising supermodes in twisted topological photonic crystal fibre (topoPCF). We show that geometrical twist induces a pseudo-vector potential, leading to topological chiral edge states.
P6
440 GHZ Bandwidth Frequency Comb via Fiber Loop Modulation, Mahrokh Avazpour, Marcos Delgado Blanco, Anil Raj Gautam and Liam P Barry, Radio and Optics Communications Laboratory, School of Electronic Engineering, Dublin City University, Glasnevin, Dublin 9, Ireland.

We present a preliminary assessment of satellite quantum key distribution (SatQKD), estimating the QKD potential between a satellite and a ground station in Waterford, Ireland, considering local effects and atmosphere using the Pirandola-Laurenza-Ottaviani-Banchi (PLOB) bound.
P8
Performance of Fibre Optical Parametric Amplifiers for QAM signals amplification, Mariia Bastamova, Vladimir Gordienko, Nick J. Doran and Andrew D. Ellis, Aston Institute of Photonic Technologies, Aston University, Birmingham, B4 7ET, UK. We numerically and experimentally characterise the required-OSNR penalty induced by a fibre optical parametric amplifier (FOPA) on 16QAM signals. We consequently demonstrate that the FOPA pump phase modulation is the key source of signal degradation.
P9
Proposal for Integrated Optical Isolator at Visible Wavelength on Silicon Nitride Waveguide Platform, Risov Das, Brian Corbett and Samir Ghosh, III-V Materials and Devices Group, Photonics Centre, Tyndall National Institute, Cork, Ireland, T12 R5CP.

Nonreciprocal phase shift (NRPS) for two different integration routes of Ce-YIG on SiN waveguide is shown.
P10
Hermite-Gaussian Image Scanning, Alexander Duplinskiy, Jernej Frank, Kaden Bearne and A. I. Lvovsky, Department of Physics, University of Oxford, Oxford, OX1 3PU, UK. We experimentally demonstrate how combining a recently developed superresolution Hermite-Gaussian imaging technique with a traditional image scanning approach yields superior lateral resolution and image quality compared to either method alone.
P11
Generalization Capabilities of Machine Learning-based PDM Equalization, Samuel Lennard, Fabio A. Barbosa and Filipe M. Ferreira, Optical Networks Group, Dept.

Guiomar and Gil M. Fernandes, Instituto de Telecomunicações and University of Aveiro, Campus Universitario de Santiago, 3810-193, Portugal. Using an atmospheric chamber, we experimentally compare EDFA and SOA pre-amplifiers for turbulence mitigation in a real-time 10 Gbps FSO system. While both offer similar fading mitigation, the EDFA superior linearity increases the system reliability.
P13
Feasibility of Direct Quantum Communications Between the UK and Ireland via 224 km of Underwater Fibre, Ben Amies-King1,†,*, Karolina P. Schatz1,†, Haofan Duan1,†, Ayan Biswas1, Jack Bailey2, Adrian Felvinti2, JaimesWinward2, Mike Dixon2, Mariella Minder1,3, Rupesh Kumar1, Sophie Albosh1, Marco Lucamarini1, 1School of Physics, Engineering & Technology and York Centre for Quantum Technologies, Institute for Safe Autonomy, University of York, YO10 5FT York, UK, 2euNetworks Fiber UK Limited, 5 Churchill Place, London, E14 5HU, UK, 3Department of Electrical Engineering, Computer Engineering and Informatics, Cyprus University of Technology, Limassol, 3036, CY † These authors contributed equally to this work.

When microsurgery tools are employed in invasive intraocular procedures, the confined space inside the eye represents a patient safety challenge. We propose an integrated fiber sensor, which measures micrometer resolution spacing between tool and tissue.
P15
Solid-State Polymer Based 1D and 2D Tunable Random Laser in Visible Spectrum, Bhupesh Kumar1,2, Sebastian A. Schulz2 and Patrick Sebbah1, 1Department of Physics, The Jack and Pearl Resnick Institute for Advanced Technology, Bar-Ilan University, Ramat-Gan, 5290002 Israel; 2SUPA, School of Physics and Astronomy, University of St. Andrews, Fife, KY16 9SS, UK. We report tunable random lasing in 2D and 1D solid-state polymer-based dye-doped random lasers. In 2D configuration, we show that the laser emission can be red-shifted by either decreasing scatterer density or increasing pump area. In 1D system, we demonstrate temperature-controlled spectral tunability of a partially-pumped single-wavelength random laser.
