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

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.

Synthesis of Self‐Healing Microbeam by Superposition of Self‐Decelerating Corner‐Diffraction Beams
Quasi‐nondiffracting (QND) beams boast long‐range propagation and self‐healing capabilities but require complex beam‐forming platforms. In contrast, the photonic nanojets (PNJs) boast simple platforms but are utilized primarily for near‐field applications. This work aims to hybridize the QND and PNJ beam concepts with a view to realize microscale, self‐

Monolithically Integrated Fourier Injected REsonator (FIRE) for Passive Coherent Laser Combination
Semiconductor diode‐based Fourier Injected REsonator (FIRE). The concept of free space FIRE, formerly known as the self‐Fourier cavity, is demonstrated for the first time on a chip‐scale device. A very high laser array coherence (97.7% fringe visibility), corresponding to single out‐of‐phase supermode operation, is reported.
