Chalcogenide glass-based rib ARROW waveguide
Source abstract
Abstract
Abstract This work is focused on the fabrication of a chalcogenide rib ARROW structure. Three chalcogenide films of two different compositions (Ge33As12Se55 and Ge28Sb12Se60) were stacked on a silicon substrate, and the upper layer etched by a reactive physical process to ensure linear behavior. Cross-section (or lateral) light confinement at 1.55 μm was obtained and gross optical loss measurements yielded 6 dB on a 1 cm long sample.
