State‐of‐the‐Art Solar Blind and X‐Ray Photodetectors Based on Gallium Oxide

open access: yesAdvanced Photonics Research, EarlyView.
State‐of‐the‐art Ga2O3‐based solar‐blind UV and X‐ray photodetectors (PDs) are reviewed. Benchmark plots compare responsivity versus specific detectivity for UV PDs (photoconductors, photovoltaic, Schottky, heterojunction, avalanche, and phototransistor types) and sensitivity versus response time for X‐ray detectors based on Ga2O3 bulk crystals, thin ...

Review of Coherent Anti‐Stokes Raman Scattering Nonresonant Background Removal and Phase Retrieval Approaches: From Experimental Methods to Deep Learning Algorithms

open access: yesAdvanced Photonics Research, EarlyView.
Coherent anti‐stokes Raman spectroscopy (CARS) enables high‐resolution vibrational imaging, yet non‐resonant background (NRB) distorts spectral fidelity. This review highlights NRB removal methods—from experimental strategies and numerical algorithms to emerging deep learning techniques.

Realizing Multispectral Fabry–Perot Structural Color Filters Based on Optical Nanostructures on a Complementary Metal Oxide Semiconductor Chip

open access: yesAdvanced Photonics Research, EarlyView.
A new paradigm for the implementation of Fabry–Perot color filters, which may be fabricated using complementary metal oxide semiconductor‐processing with significantly fewer process steps than the state of the art is demonstrated. It is streamlining and economizing the manufacturing process associated with commercial products incorporating color ...

Advances in Mode (De)Multiplexing Technologies via Circularly Symmetric Structured Light Beams

open access: yesAdvanced Photonics Research, EarlyView.
This review presents a comprehensive overview of mode (de)multiplexing technologies using circularly symmetric structured light beams, encompassing strategies of beam splitter combinations, multiorder diffractive gratings, optical coordinate transformations, angular dispersion lenses, multilayer cascaded modulations, and multidimensional hybrid (de ...
