Nano-photonic devices fabricated from chalcogenide glasses

Gai, Xin

Description

Chalcogenide glasses have been widely used for all-optical processing. Our team identified a particular chalcogenide glass, with composition Ge{u2081}{u2081}.{u2085}As{u2082}{u2084}Se{u2086}{u2084}.{u2085} (Ge{u2081}{u2081}.{u2085}), as having very the best properties for nonlinear waveguides. The material has a nonlinear refractive index about three times higher than ASZS3 and negligible two photon and free carrier absorptions. In particular, its optical properties have been shown to be...[Show more]
