<title>Integrated GaAs optoelectronic receiver</title>

Abstract

An integrated optoelectronic receiver has been developed for Monolithic Microwave Integrated Circuit (MMIC)-based phased array antenna applications. The device enables the distribution of MMIC control signals, necessary for the steering of the antenna, by fiber optics rather than electrical cables. This method of control signal distribution minimizes the weight of the antenna system, and virtually eliminates any electromagnetic interference. Additionally, the fiber optic cable greatly improves the mechanical flexibility of routing the control signals. The Monolithic Optical REceiver (MORE) was developed under contract with Honeywell. The device features fully monolithic integration of a photodetector, a low noise amplifier, and a digital demultiplexer on a GaAs substrate. The MORE can operate at user-selectable data reception rates ranging from 10 to 400 Mbps, has built-in clock recovery, and is addressable. The MORE can also be operated in a continuous reception mode or data can be sent in a bursted mode. This paper will describe the features of the MORE and the applications for which it is already being used in both space and terrestrial applications.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
