This letter demonstrates a compact, very low power consumption, and low crosstalk multimode interference coupler-based polymer thermooptic photonic switch. The fabricated thin-film small-area heater confirmed the simulation results with operating power consumption as low as 8.9 mW. The switching crosstalk obtained was less than -23 dB.
