Abstract(in English) | We demonstrated a Mach-Zehnder (MZ) interferometer-type photonic switch using multi-mode interference (MMI) couplers with InAlGaAs/InAlAs compound semiconductor materials. Hybrid-waveguide structure with different etching depths was adopted for MMI couplers and other parts of the waveguides for polarization-independent operation. As a result, low-crosstalk switching operation of less than -20dB was confirmed regardless of polarizations of an input light. Switching currents were 5.25 and 4.75mA for TE and TM modes of the input light, respectively. High-speed switching operation with about 3 nano-second transition times was also confirmed. |
