Abstract

Dissipative solitons formed in Kerr microresonators offer the promise of chip-scale frequency combs that can extend precision metrology outside of a laboratory environment. We explore the creation of an octave-spanning, 15 GHz repetition rate microcomb suitable for both f-2f self- referencing and optical-frequency comparisons across the near infrared. We use a simple and reliable approach to deterministically generate, and subsequently frequency stabilize, soliton pulse trains in a silica disk resonator. Efficient silicon-nitride waveguides provide a supercontinuum spanning 700-2100 nm, enabling both offset-frequency stabilization and optical- frequency measurements with >100 nW per mode. We use the stabilized comb to perform the first microcomb-mediated comparison of two ultrastable optical reference cavities to demonstrate its utility.
