Abstract: In this paper, we will describe the design of a monolithic optical time-shift network specified to steer a dual-band microwave phased array antenna at 2 and 10 GHz. In particular, we will emphasize the advantages of using 'cascade architectures' to achieve the desired bits of resolution. Finally, we will describe how different delay-times are implemented in this optical time- shifter via bias control of detectors integrated monolithically on the GaAs wafer.!2
