#DISCOVERY #RESEARCH #ChairePhotonique LMOPS - Laboratoire Matériaux Optiques, Photonique et Systèmes CentraleSupélec Université de Lorraine Institut Photonique We demonstrate a new dynamical behavior in a semiconductor laser, which is published in the high impact journal Nature Photonics. Transverse modes get spontaneously phase locked and the synchronized modes coexist with other unsynchronized laser modes. Such a partial synchronisation between interacting oscillators is also called chimera state in nonlinear systems and is here found spontaneously in a laser!

Great reading for everybody who is interested in integrated photonics.

Researchers have achieved a significant breakthrough in manipulating light at the nanoscale. Their work, published in Nature Photonics, demonstrates a novel technique to bring light waves to a complete standstill by deforming a two-dimensional photonic crystal. This finding, achieved independently by a team at Pennsylvania State University published in the same journal, holds immense potential for the development of nanophotonic devices. #electrons #light #photonics #nature https://lnkd.in/gAty8njb

'Our ambition is to have all of the visible and infrared bands together in high resolution in one inexpensive device' Professor Mohsen Rahmani in New Electronics discussing research to develop state-of-the-art camera technology which for the first time will bring high resolution to the entire range of infrared imaging. The work is being made possible through a €3m grant from the European Research Council (ERC), awarded to Professor Rahmani and his Advanced Optics and Photonics team. #ERCCoG NTU Research https://lnkd.in/ex346WEj

I'm delighted to share the exciting outcomes of our research in pioneering a novel class of microcombs: the soliton vortex comb. Yang Liu will present the work in the postdeadline session at CLEO 2024. For further details, read more in the pages of our recent publication in Nature Photonics titled 'Integrated Optical Vortex Microcomb'." https://lnkd.in/dthfBTS2 Leveraging the exceptional ultra-high nonlinearity of the aluminum gallium arsenide-on-insulator (AlGaAsOI) waveguide platform, we have successfully achieved the robust generation of soliton microcombs that can emit a cluster of light not only across the frequency dimension but also in the optical mode dimension, specifically through orbital angular momentum (OAM) modes. This breakthrough significantly enhances the versatility of microcombs, opening new avenues for advanced applications in various fields. Photons with OAM are critical in applications ranging from fundamental physics to communications. By integrating angular gratings, the microresonators can emit whispering gallery modes carrying OAM. Initially limited to monochromatic operation, the adoption of Kerr nonlinear processes allows these devices to generate broadband frequency combs with spectrally multiplexed OAM modes. However, the efficient OAM scattering induced by angular gratings conflicts with the necessity for low scattering losses for efficient comb generation. AlGaAs, with its renowned ultra-high Kerr nonlinearity, effectively compensate for these losses, enabling the production of advanced vortex combs with a wide array of optical vortices and opening new possibilities in communication and quantum applications. Thanks to all the team members for the collaborative effort, especially Jin Liu from SYSU and Qiwen Zhan from USST for driving the collaboration, Kresten Yvind and Leif Katsuo Oxenløwe for supporting the effort, Yueguang Zhou, Yang Liu, Chaochao Ye, Chanju Kim, and Yi Zheng for realizing the soliton vortex comb, Bo Cheng, Qian Can, and Peinian Huang for demonstrating the self-torque pulse synthesis.

Photonic time crystals represent a unique class of optical materials. Unlike traditional crystals, which have spatially repeating structures, photonic time crystals remain uniform in space but exhibit a periodic oscillation in time. This distinctive quality creates momentum band gaps, or unusual states where light pauses inside the crystal while its intensity grows exponentially over time. #Optics #Photonics
