Paper Abstract

Advances in optically nonlinear materials and single mode fiber technology have led to a renewed interest in integrated optics. For coherent communication fiber systems, integrated optics offer the possibility of an entirely monolithic implementation with narrow linewidth lasers, modulators, detectors, frequency shifters and optical switches. With III-V semiconductors, optical functions and associated electronics for drivers and detectors can be on the same opto-electronic chip. Recent advances in nonlinear integrated optics also hold promises for applications in ALL-OPTICAL processing and interfacing of fiber signals. Power dependent nonlinear couplers, nonlinear distributed feedback gratings, optically tunable filters, bistable integrated gratings and logic gates are all possible applications of integrated optics in communication systems resulting from a better understanding of nonlinear guided mode behavior. New organic (such as liquid crystals) or semiconductor materials (multiple quantum wells (MQW) for example) in an integrated optics context may provide the properties needed to make all-optical processing viable in the next generation devices. As an example 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 fiber systems since the lack of resonators ensures good stability in actual operation.
