BDLUT: Blind image denoising with hardware‐optimized look‐up tables

open access: yesJournal of the Society for Information Display, EarlyView.
BDLUT(‐D) is a novel blind denoising method combining optimized lookup tables (LUTs) with hardware‐centric design. While BDLUT describes the LUT‐based network architecture, BDLUT‐D represents BDLUT trained with a specialized noise degradation model. Designed for edge deployment, BDLUT(‐D) eliminates neural processing units (NPUs) and functions as a ...

Discrete Chiral Ballistic Polariton Laser

open access: yesLaser &Photonics Reviews, EarlyView.
Planar microcavities in the strong light–matter coupling regime exhibit exciton‐polariton modes with a strong chiral response toward circularly polarized light. This feature is exploited alongside inherent spin‐orbit coupling of cavity light to generate giant discrete optical vortices in polygonal arrays of exciton‐polariton condensates.

Narrow Linewidth Laser Based on Extended Topological Interface States in 1D Photonic Crystals

open access: yesLaser &Photonics Reviews, EarlyView.
This work introduces a novel 1D‐TISE‐PhC semiconductor laser structure achieving uniform photon distribution, reduced linewidth (126 kHz), robust single‐mode performance (SMSR up to 50 dB), precise wavelength control, and tolerance to fabrication variations, demonstrated experimentally in an eight‐channel array.

Space‐Time‐Modulated Metasurface Enabled High‐Performance Near‐Field Focusing with Enhanced Phase Modulation

open access: yesLaser &Photonics Reviews, EarlyView.
This study leverages STM technology to enhance NFF performance by enabling continuous phase control at the +1st harmonic without increasing hardware complexity. It overcomes the limitations of conventional 1‐bit TMs caused by phase quantization errors and demonstrates that even compact arrays can achieve effective focusing, highlighting the strong ...
