Χ<sup>2 </sup>Optical Frequency Comb by Cavity Phase Matching

ORAL

Abstract


Micro-resonator-based optical frequency combs (OFC) are portable frequency standards with high beat note frequencies, which can be used for high precision spectroscopy, navigation, telecommunication and astronomy. Compared to the conventional micro-ring resonators, the resonators can benefit from much stronger nonlinearity for the comb generation from optical parametric down conversion processes, with new physics in these platforms.
Here we report the optical frequency comb generation by cavity phase matching, where the large phase matching bandwidth enables broad comb span over 80 nm. The sheet cavity design allows high slope efficiency and peak output power, which exceed 22.6 % and 14.9 kW. Comb lines are measured to be equidistant within the instrument-limited accuracy. Therefore, we show that the sheet parametric oscillator is a promising candidate for portable integrated optical frequency comb generation.
