Abstract

We demonstrate a fully packaged hybrid integrated laser and a soliton microcomb with frequency actuation bandwidth of more than 10 MHz and ultra-low laser frequency noise. The flat frequency response in the range of >1 MHz and the optical laser frequency chirp range of >1 GHz are compatible with high-resolution continuous wave frequency modulated distance ranging and distributed fiber optic sensing without any linearization or pre-distortion. The features of a novel laser system assembled in 14-pin butterfly package are enabled by the ultra-low loss silicon nitride platform and monolithically integrated piezo-electric actuators.
