Abstract : Optical techniques for spectral domain processing (SDP) by frequency mixing of laser beams in optical waveguides have been investigated; A theoretical model for calculating nonlinear coefficients and dispersion characteristics of asymmetric quantum wells has been developed and applied in a novel design for a frequency conversion device. A new quasi-phase-matching approach to obtaining high conversion efficiency in optical waveguides has been proposed and analyzed. The quantitative analysis predicts conversion lengths as short as 112 microns with a power density of 1 MW/ cm2 at the optical pump wavelength of 1.3 microns. A dense wavelength-division-multiplexed (WDM) network which makes use of the frequency conversion device to obtain rapid switching between channels has been designed. Nonlinear devices in each node convert an incoming carrier to any frequency in an entire wavelength regime in a few nanoseconds, ensuring a low latency time in the network. (MM)
