Optical control of a GaAs MMIC transmit/receive module

Experimental results are reported for optical gain control and optical pulse-code modulation (PCM) of a GaAs microwave monolithic integrated circuit (MMIC) distributed amplifier intended for reconfigurable phased-array antenna use. The control signal was generated by a low-cost LED, and a multifinger MESFET was utilized as a photodetector. The amplifier gain was varied by 15 dB as a function of the optical intensity over the frequency range of 5-8-GHz. Pulse-code modulation was obtained using a semiconductor laser.<<ETX>>
