8.1 Gbps PAM8 Long-Wave IR FSO Transmission using a 9.15-µm Directly-Modulated QCL with an MCT Detector

Not Accessible

Your library or personal account may give you access

Abstract

We experimentally demonstrate a Long-Wave IR FSO link with a 9.15-µm directly modulated quantum cascade laser at room temperature. Up to 8.1 Gb/s PAM8 transmission over 1.4 meter is achieved with a wideband MCT detector.
