Abstract :
A 1 × 3 Mach-Zehnder-based electrooptic switch in silicon is presented, which employs only two p-i-n phase shifters and possess a simple control manner. Average crosstalk level and extinction ratio are -21.9 and 22.9 dB, respectively, at 1550-nm wavelength. The influences of free carrier absorption (FCA) and fabrication error on the crosstalk of the switch are analyzed according to the theory and experimental results.
