N2 - Multimode interference (MMI) waveguide switches show promise for switch in optical packet switching (OPS). In this work, we fabricated 1x4 InGaAsP/InP MMI waveguide switch device which consists of a 1 x 4 MMI splitter, 4 equally spaced single-mode waveguides with phase shifters, and a 4 x 4 MMI combiner. Good crosstalk and extinction ratio of -14.47 dB and 23.39 dB, respectively, are obtained. In addition, we experimentally demonstrate dynamic switching, and the rise and fall time of 1.4 ns and 1.2 ns, respectively, are obtained.
