Non-linear chalcogenide glasses and technologies for the development of ultra-fast chip-scale optical devices

Abstract

Chalcogenide glasses are novel highly non-linear materials for photonics. Modification of optical glasses by high-intensity femtosecond pulses is a novel fast developing technology based on non-linear effects. In this paper, the advantages of using the method of femtosecond modifications for the fabrication of highly non-linear 3D photonic structures in bulk chalcogenide glasses are overviewed. Design and modelling of chip-scale highly non-linear structures for all-optical signal processing are discussed.
