In this paper, a fast optical switch working at 1550 nm that has a very short response time on the order of picoseconds is proposed. The optical switch has a very compact size of 10.14×10.14 μm2 and a concise structure consists of 16×16 In1-xGaxAsyP1-y-InP rods in air. The structure of the switch is optimal designed by analyzing its equi-frequency contours and bandgaps. Its performance is confirmed by finite-difference time-domain simulations. The designed optical switch may find important applications in the photonic integrated circuits..
