Optical computing and related microoptic devices.

We investigate scaling with the cross-sectional area of energy and speed for optical devices and of optical design, speed, and thermal dissipation for device arrays. Theory and experiments clearly point to lower energy and faster speed for smaller devices and to simpler optical design, smaller propagation time delays, and higher thermal dissipation capability for smaller array sizes. We conclude that the development of high speed digital optical processors will depend on small devices interconnected by microoptic systems.
