Abstract
Advances in optically nonlinear materials and single mode fiber technology have led to a renewed interest in integrated optics. Recent advances in nonlinear integrated optics also hold promises for applications in ALL-OPTICAL processing and interfacing of fiber signals. Here we present some of our work on all-optical modulation and logic gates in silicon based channel waveguides at wavelengths of 1.32 and 1.55 micrometers. PicoJoule switching energies and subpicosecond initiation times make these waveguide devices attractive for single mode fiber systems since the lack of resonators ensures good stability in actual operation.
