Abstract

<p>Chalcogenide glass is used to develop all-optical signal processing devices for photonic equivalent of electronic chips, which are able to demultiplex data signals and convert the carrier wavelength. The chalcogenide glass planer waveguides are developed with lengths up to 24 cm and optical losses as low as 0.05 dB/cm at 1,500 nm. Cross-phased modulaiton is a nonlinear optical process by which wavelength conversion can be achieved using chalcogenide glass waveguides. The chalcogenide waveguides offer convenient platform for realizing a functionality using Kerr-nonlinearity-based four-wave mixing. Chalcogenide glasses also exhibit various types of photo-induced phenomena that have been used in the formation of various optical components such as Bragg gratings. The mid-infrared transparency of chalcogenide glass is of significant interest to signal processing devices.</p>
