An Efficient Diamond Raman Amplification Scheme Based on Adaptive Temporal Synchronization

Advanced Photonics Research, EarlyView.
This work reveals an adaptive temporal synchronization effect in delayed diamond Raman amplification, where the Stokes pulse shifts toward the fundamental peak. A periodic amplification scheme based on this phenomenon enables efficient pump recycling and enhanced energy conversion, offering a robust, delay‐tolerant strategy for advanced nonlinear ...

Bound States in the Continuum in Metasurface Absorbers: A Comparison with Metasurfaces

Advanced Photonics Research, EarlyView.
Bound states in the continuum (BICs) offer a powerful mechanism for enhancing light–matter interactions. This work systematically investigates the radiation characteristics of BICs under both transmission and reflection configurations using multipolar analysis.

Enhanced Trapping with an Optimized Graphene‐Based Bowtie Plasmonic Nanotweezer: Design, Analysis, and Bioanalytical Applications

Advanced Photonics Research, EarlyView.
A graphene‐based bowtie plasmonic nanotweezer is designed and optimized using particle swarm optimization and transfer matrix analysis. The structure achieves strong field confinement, delivering trapping forces up to 6 nN W−1 for 10 nm bioparticles with sixfold lower power requirements than conventional designs.

Computational Analysis of a GST‐Based Long‐Wave Infrared Microring Resonator on a ZnSe Platform as a Photonic Sensor

Advanced Photonics Research, EarlyView.
A Ge2Sb2Te5 (GST)‐based microring resonator is designed and simulated on a ZnSe‐platform that operates in the long‐wave infrared (LWIR) wavelength of 8 μm. The structure demonstrates strong power confinement and high Q‐factor. GST resonator is used for gas and biosensing applications.
