Abstract
The overall performance of integrated circuit systems is enhanced by the use of optical drivers and receivers to send and receive information between the devices on the chip and between individual chips in a system. A single substrate of gallium arsenide employs both the high carrier mobility properties and the electrooptical signal conversion properties on a single substrate to provide both high performance electrical properties and high density and high performance communication properties.
