Radiofrequency diode

A variety of phased array systems have been fabricated based on polsrmeric electrooptic materials (141,142). One configuration is based on the photonic phase shifter shown in Figure 10. This provides a very linear phase shift as a function of control d-c voltage. Optical signals of controlled phase are thus sent to various radiating antenna elements. The optical signals are converted to radiofrequency signals by diode detectors.
