Stimulated Raman Scattering with Optical Vortex Beams

Advanced Photonics Research, EarlyView.
This study presents exact analytical expressions for stimulated Raman scattering with Laguerre‐Gaussian beams, revealing signal dependence on topological and hyperbolic momentum. The results provide a theoretical foundation for coherent Raman imaging and detecting orbital angular momentum of light via structured light in nonlinear optics.

Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

Advanced Photonics Research, EarlyView.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

Technical Language Processing for Telecommunications Specifications [PDF]

arXiv
Large Language Models (LLMs) are continuously being applied in a more diverse set of contexts. At their current state, however, even state-of-the-art LLMs such as Generative Pre-Trained Transformer 4 (GTP-4) have challenges when extracting information from real-world technical documentation without a heavy preprocessing.

Microwave Monitoring by Compact Carbon Nanotube Photo‐Thermoelectric Sensors Beyond the Diffraction Limit Toward Ultrabroadband Non‐Destructive Inspections

Advanced Sensor Research, EarlyView.
This work overcomes long‐standing crucial technical difficulties in miniaturizing micro‐wave detectors, caused by the longer‐wavelength diffraction limit, with carbon nanotube (CNT) film photo‐thermoelectric sensors. The CNT film sensor exhibits sensitive micro‐wave detection operations with signal‐to‐noise ratios over 1400 at compact device sizes ...
