TLDR
A series of chalcogenide glasses from the As-S-Se system that is designed to have strong nonlinearities are synthesized and measurements reveal that many of these glasses offer optical Kerr non linearities greater than 400 times that of fused silica.Abstract:
We have synthesized a series of chalcogenide glasses from the As–S–Se system that is designed to have strong nonlinearities. Measurements reveal that many of these glasses offer optical Kerr nonlinearities greater than 400 times that of fused silica at 1.25 and 1.55 µm and figures of merit for all-optical switching greater than 5 at 1.55 µm.read more

Nonlinear silicon-on-insulator waveguides for all-optical signal processing
TL;DR: Values up to gamma=7 x 10(6)/(W km) for the nonlinear parameter are feasible if silicon-on-insulator based strip and slot waveguides are properly designed, and this enables ultrafast all-optical signal processing with nonresonant compact devices.
