Abstract

A microring notch filter with a thermally-tunable Mach-Zehnder coupler is demonstrated. The thermal tuning is enabled via an intrinsic thermal resistor based on a lateral p-i-p junction across a silicon waveguide. Experimental results show that the extinction ratio of the notch filter can be increased by >10 dB with a current of 0.4 mA.
