This letter demonstrates the design and experimental verification of a very low-power consuming, polarization-independent, and high-speed polymer Mach-Zehnder 2 × 2 photonic switch. This thermooptic switch operated with less than 4 mW of power consumption via a small-area heater. This device is, to the author's best knowledge, the most efficient and practical polymer photonic switch operating with polarization independence and low crosstalk of less than 25 dB.
