We fabricated an InAlGaAs/InAlAs/InP semiconductor photonic switch with a Mach-Zehnder interferometer (MZI) and multi-mode interference (MMI) couplers for low-power consumption operation. As a result, very-low-current switching operation was attained with as low as 3.5 mA experimentally. High-speed switching operation with nano-second-order switching time was also confirmed.
