Abstract
In this paper, the performance of a germanium-doped silicon optical phase shifter with vertical PN junction has been investigated. The proposed phase shifter is simulated using a process simulation tool, and 2D carrier distribution has been used to calculate the phase shifter performance metrics. The designed phase shifter is integrated into a Mach–Zehnder interferometer structure, and the transfer characteristics are plotted. The proposed phase shifter has a phase shift of , of , insertion loss of , and 3 dB bandwidth of at 5 V reverse bias.
