Photosensitivity of As2S3 thin films at 1.5 µm

Not Accessible

Your library or personal account may give you access

Abstract

The chalcogenide glass As2S3 is shown to be photosensitive to a wavelength of 1.5 µm, which is a problem for the development of chalcogenide-based integrated optical devices. Self-writing experiments demonstrate the photosensitivity to pulsed guided light inside slab waveguides and ridge waveguides.
