Query: Octave-wide phase-matched four-wave mixing in dispersion engineered
  crystalline microresonators   In this Letter, we report phase-matched four-wave mixing separated by over
one-octave in a dispersion engineered crystalline microresonator. Experimental
and numerical results presented here confirm that primary sidebands were
generated with a frequency shift up to 140 THz, and that secondary sidebands
formed a localized comb structure, known as a clustered comb in the vicinity of
the primary sidebands. A theoretical analysis of the phase-matching condition
validated our experimental observations, and our results good agree well with
numerical simulations. These results offer the potential to realize a frequency
tunable comb cluster generator operating from 1 um to mid-infrared wavelengths
with a single and compact device.
