Abstract :
A thermooptic 2×2 switch based on the total internal reflection effect is demonstrated. The device, made of ultraviolet curable fluorinated polymer, has an increased half-branch angle of 5°. The purpose of a large half-branch angle is to overcome the volume relaxation phenomenon, which is an intrinsic characteristic of polymers. The device successfully decreases the crosstalk below -40 dB in both the cross and bar states. The fabricated device has a power consumption of only 66 mW in the bar state.
