Octave-spanning tunable parametric oscillation in crystalline Kerr microresonators

Abstract

Through degenerate Kerr four-wave mixing in ultrahigh-Q crystalline microresonators made of magnesium fluoride, tunable conversion of a compact, low-power telecommunications laser over an entire optical octave from 1,083 nm to 2,670 nm, with signatures of mid-infrared sidebands at almost 4,000 nm, is shown.
