Abstract

This paper presents an optically controlled reflection type RF phase shifter using microstrip rate race coupler fabricated on silicon substrate. Optically controlled reflection type RF phase shifter can be realized by creating an optically induced resistive termination by a laser spot at the open end of controlling ports in rat-race coupler. To simulate the transmission behavior of proposed structure, the optically induced load at the open end of the port has been modeled as a resistive termination. The simulation results show that the phase and amplitude of the output RF signal can be controlled by optical terminations at different intensities and can be used as an optically controlled RF phase shifter.
