Paper Abstract

Integrated optical circuits will be used in high performance optical systems in the future. This paper reviews progress towards making such circuits using semiconductor substrates. Discrete GaAs/GaAlAs devices have been made and have shown low propagation loss (<2dB/cm), low operating voltage (9V for a Tr phase shift) and the potential for high speed (<500ps rise time). InP devices are less well developed but show promise. The proposed implementation of a laser/waveguide component is described, and the prospect of other integrated optical circuits, including matrix switches, is discussed.
