Advancing Terahertz System Characterization and Performance Modeling Drawing from my extensive experience in Explosive Ordnance Disposal and technology training programs, I'm excited to share insights from recent advancements in terahertz (THz) technology. The field is rapidly evolving, with significant implications for security, medical imaging, and materials science. The paper "Terahertz System Characterization and Performance Modeling" presented at the SPIE Conference delves into the complexities of THz system design. It emphasizes the critical role of active sources, specialized optics, and detectors in achieving optimal performance. By comprehensively modeling these components—addressing factors such as coherence, aberrations, dynamic range, and noise—researchers can significantly enhance the capabilities of THz imaging systems. Key Takeaways: Enhanced Detection and Imaging: Advancements in THz technology are leading to more precise detection and identification of concealed objects, thereby bolsteringsecurity measures. Performance Optimization: Detailed modeling helps identify and mitigate non-ideal performance factors, ensuring the reliability and efficiency of THz systems. With my background in handling high-stakes situations and cutting-edge technology, I am particularly excited about how these advancements will shape the future of imaging and detection systems. The potential benefits across various sectors are immense, and I look forward to contributing to this dynamic field. #TerahertzTechnology #ImagingSystems #SPIE #Innovation #ResearchAndDevelopment #RaySecur

Can sound waves be used to deflect light? Yes! According to a recent study published in Nature Photonics, researchers from Germany were able to create an air grading using acoustic waves and achieved 50% deflection efficiency of high peak power ultrashort laser pulses. This is a very intriguing finding with some interesting potential applications. https://lnkd.in/gcXD4qUs

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.

[PDF] Mono-Cycle Photonics and Optical Scanning Tunneling Microscopy: Route to Femtosecond Ångstrom Technology N. Karasawa, Y. Mizuta, X. Fang (auth.), Professor Mikio Yamashita, Professor Hidemi Shigekawa, Professor Ryuji Morita (eds.) digsell https://lnkd.in/e4veQxZE “Mono-Cycle Photonics and Optical Scanning Tunneling Microscopy” deals with both the ultrashort laser-pulse technology in the few- to mono-cycle region and the laser-surface-controlled scanning-tunneling microscopy (STM) extending into the spatiotemporal extreme technology. The former covers the theory of nonlinear pulse propagation beyond the slowly-varing-envelope approximation, the generation and active chirp compensation of ultrabroadband optical pulses, the amplitude and phase characterization of few- to mono-cycle pulses, and the feedback field control for the mono-cycle-like pulse generation. In addition, the wavelength-multiplex shaping of ultrabroadband pulse is described. The latter covers the CW-laser-excitation STM, the femtosecond-time-resolved STM and atomic-level surface phenomena controlled by … Read More » https://lnkd.in/e3zd2B7J...
