Gb/s LWIR FSO Transmission at 9.6 µm using a Directly-Modulated Quantum Cascade Laser and an Uncooled Quantum Cascade Detector

Not Accessible

Your library or personal account may give you access

Abstract

Record 11 Gb/s LWIR FSO transmission is demonstrated with a 9.6-µm directly-modulated QCL and a fully passive QCD without cooling, surpassing the previous bitrate record of DM-QCL-based FSO in this spectral window by 4 times.
