Abstract :
Chalcogenide glasses are an important class or amorphous materials with applications that include phase- change optical memories, solar cells, and optical waveguides. Particularly interesting for optical applications is their good transparency in the mid-infrared combined with their high linear and nonlinear refractive indices. This last property has motivated interest in the use of chalcogenide waveguides for all-optical processing of high-speed telecommunications signals.
