Query: Optical-frequency measurements with a Kerr-microcomb and photonic-chip
  supercontinuum   Dissipative solitons formed in Kerr microresonators may enable chip-scale
frequency combs for precision optical metrology. Here 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.
This is achieved through 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 to 2100 nm, enabling both offset-frequency
stabilization and optical-frequency measurements with >100 nW per mode. We
demonstrate the stabilized comb by performing a microcomb-mediated comparison
of two ultrastable optical-reference cavities.
