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.

Engineering Reports, Volume 7, Issue 1, January 2025.ABSTRACT Due to the long transmission distance of the constellation network represented by the low‐orbit satellite system, the satellite‐to‐ground link is subject to large path loss and limited communication performance. This paper uses multi‐satellite and multi‐beam joint transmission technology to form a virtual multiplex network with ground multi ...
