Abstract
Summary from only given. Bridging the so-called last mile in telecommunication networks has revived interest in free space optical (FSO) data transmission links. Under low visibility conditions the reliability of these links is limited due to high atmospheric scatterings rates. In contrast, mid-infrared (MIR) links promise higher stability. Such links were recently demonstrated using quantum cascade (QC) lasers, a versatile semiconductor laser system for the MIR band ( 3.5 24 /spl mu/m). In this talk we present the first atmospheric transmission of complex data (multimedia satellite channels) with a MIR QC laser and compare the performance of this link to one operating in the near infrared.
