A novel fast switching photonic phase shifter for ka-band

Photonic phase shifters for Ka-band have been used in satellite communication and in many other communication systems. In these applications speed, bandwidth, power consumption and size have become more significant. In communication systems beamforming with fast switching phase shifters has special importance for Ka band. Integrated microwave photonics allow the implementation of phase shifters. We propose a novel architecture for photonic phase shifter with switching time of about 30 to 52 fs .as compared to existing architecture. The phase shifter architecture has been designed with DC tunable ring resonator, S-bend waveguide switch and nanowire DC tunable phase shifter. The designed nanowire waveguide for DC tunable ring resonator, S-bend waveguide switch and DC tunable phase shifter has been simulated using OptiFDTD as well as with MATLAB.
