Abstract

Quantum well modulators and photodetectors are one attractive option for large scale integration of arrays of optical inputs and outputs in information processing systems. Optics is fundamentally attractive because it offers basic physical advantages in interconnections, and may allow novel architectures of information processing systems not well-suited to electronics alone. In the past, large arrays of quantum well devices have been used in experimental systems, and more recently technologies have emerged that have allowed "smart" arrays incorporating electronics both for added functional complexity and reduced optical energy requirements. The FET-SEED technology, for example, has integrated GaAs field effect transistors with quantum well modulators and detectors for high speed circuits with sophisticated functions, and has already been used to fabricate multi-project wafers for experimental use by a broad range of users.
