An Ultra‐Wideband Metasurface Perfect Absorber Based on Hybrid Absorption Modes

Advanced Photonics Research, EarlyView.
A Ge2Sb2Te5 metasurface absorber enables polarization‐independent, ultrabroadband (UV–NIR) light absorption with high angular tolerance. Its performance stems from overlapping electric and magnetic dipole resonances in a symmetric structure, achieving 94% average absorption and maintaining 83% even at 70° incidence, promising for integrated ...

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.

Inverse‐Designed on‐Chip Terahertz Three‐Channel Mode and Wavelength Division Demultiplexer

Advanced Photonics Research, EarlyView.
An ultracompact terahertz demultiplexer is developed using a hybrid inverse design that combines genetic algorithms with topology optimization. The device enables simultaneous mode‐ and wavelength‐division multiplexing within a footprint smaller than two wavelengths.
