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.
