Polarization-independent and low-current operation of InAlGaAs/InAlAs Mach-Zehnder interferometer-type photonic switch with hybrid-waveguide structure for optical packet switching

We demonstrated a polarization-independent Mach-Zehnder interferometer-type photonic switch with very-low-current of about 5mA. Furthermore, a few nano-second switching response time was also confirmed which suits for application to optical packet switching.
