Spectral-Domain Optical Processing Techniques

Abstract

Optical techniques for spectral domain processing (SDP) have been investigated. A computer model for the design of nonlinear devices for frequency mixing in multiquantum well (MQW) materials has been developed. The model has been used to calculate nonlinear coefficients for mixing of pump lasers at wavelengths near 1.3um and 1.55 um to produce and output near 8.05um. A device length for conversion of 0.6 mm is predicted for a pump power density of 106W/ cm2. A quasi-phase-matching scheme for obtaining high conversion efficiency in a dispersive semiconductor material has been devised. An N-dimensional hyper cube network configuration making use of the frequency conversion devices has been propose The scheme allows for all-optical transmission of data from source node to-destination node without optical-to-electrical conversion.
