Signal Processing with Degenerate Four-Wave Mixing

摘要

The original goals of this program were: 1. To demonstrate degenerate four-wave mixing in planar waveguides, 2. To fabricate nonlinear organic waveguides using the Langmuir-Blodgett (L-B) technique, and 3. To demonstrate all-optical signal processing based on degenerate four-wave mixing. During the course of this program, it became clear that nonlinear organic waveguides based on L-B deposition techniques would never exhibit losses low enough for guided-wave degenerate four-wave mixing. As a result, it was decided: 4. To develop semiconductor-doped glass waveguides, 5. To demonstrate degenerate four-wave mixing in these waveguides, and 6. To demonstrate all-optical signal processing in semiconductor-doped waveguides.
