QCL‐Based Cryogen‐Free THz Optical Wireless Communication Link
Laser &Photonics Reviews, Volume 19, Issue 6, March 18, 2025.A novel QCL‐based, cryogen‐free, and transportable wireless communication system is presented operating at 2.83 THz. The QCL device is mounted in a compact Stirling refrigerator, while a room‐temperature graphene‐based FET is used as a receiver, implementing a binary on‐off keying (OOK) modulation scheme with Manchester encoding.

Multiple Narrowband Bidirectional Self‐Powered Organic Photodetector with Fast Response
Laser &Photonics Reviews, Volume 19, Issue 1, January 8, 2025.Organic photodetectors(OPDs) with multiband, fast response are presented. These devices exhibit incidence direction‐dependent, narrow‐band spectral response from UV to NIR. Notably, their bandwidth surpasses 300 kHz, the fastest among same type devices reported to knowledge.

Robust Connectivity in 6G Enabled Indoor VLC Networks Using Intelligent Reflecting Surfaces
IET Communications, Volume 19, Issue 1, January/December 2025.Visible light communication (VLC) in 6G optical networks offers high data rates with extended network coverage. The challenge is that these VLC networks are susceptible to signal obstructions that lower line‐of‐sight (LoS) link quality. This paper proposes a novel framework that uses Intelligent reflecting surfaces, which provide improved non‐LoS ...
