Signal Processing with Degenerate Four-Wave Mixing

摘要

A major part of our research program in the last year has been the continuation of research into the semiconductor-doped glass material system. Bulk DFWM an photoluminescence experiments on these materials determined that they have a large nonlinear index of refraction (n(2) approx 10 to the minus 14th power sq m) with fast response times (r less than 16 psec) required for high speed optical signal processing. Along with collaborators in the University of Galsgow we successfully developed a successful ion-exchange (Na+:K+) technique for producing low-loss optical waveguides in these materials, the details of which are in the enclosed reprint.
