Laser Frequency Drift Stabilization using an Integrated Dual-Mode Locking Si3N4 Waveguide Reference Cavity

We demonstrate an integrated Si3N4 waveguide resonator designed as a dual-mode locking (DML) cavity that stabilizes laser frequency to 1.7×10-10 Allan deviation in a 1000-second average measurement with a temperature sensitivity of 187.56 MHz/K.
