We propose a polarization-independent silicon wire-waveguide directional coupler optical switch (DC-OS) by adjusting the propagation constant difference between the guided modes. The thermo-optic (TO) switching power consumption is as low as 18.5mW. This polarization-independent DC-OS is expected to be valuable for optical interconnection in silicon photonics.
In this letter, we demonstrated a Mach-Zehnder interferometer-type photonic switch using multimode interference (MMI) couplers with InAlGaAs-InAlAs compound semiconductor materials. A 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...
