Abstract

We have proposed a novel 2 × 2 optical switch using multimode interference (MMI) coupler. This switch comprises four arms, located between two MMI couplers, and works by controlling a phase shifter, situated in each arm. Compared with conventional Mach-Zehnder type of optical switches, BPM simulation of this device predicted a high tolerance to fabrication errors. We fabricated the device with silica waveguides, and confirmed that it functioned with an insertion loss of 4.1 dB and an extinction ratio of about 20dB.
