Free-space optical transmission of multimedia satellite data streams using mid-infrared quantum cascade lasers

Experimental results for an optical free-space high-speed link using direct modulated mid-infrared ( lambda = 8.1 mu m) quantum cascade lasers are presented. A total of 800 digitally encoded multimedia channels were transmitted. The reliability of the system against weather influence (fog) was exper...

Zusammenfassung:	Experimental results for an optical free-space high-speed link using direct modulated mid-infrared ( lambda = 8.1 mu m) quantum cascade lasers are presented. A total of 800 digitally encoded multimedia channels were transmitted. The reliability of the system against weather influence (fog) was experimentally compared to that of a near-infrared ( lambda = 0.85 mu m) link.
