Abstract

We demonstrate Kerr-frequency-comb generation with photonic-crystal-reflector (PCR) resonators, which is nanofabricated in a Fabry-Perot geometry. The group-velocity-dispersion (GVD) engineered photonic-crystal reflectors counteract the strong normal GVD of rectangular waveguide fabricated on a thin, 450-nm silicon nitride device layer. The reflectors provide the resonators with both the high optical quality factor and anomalous GVD required for Kerr-comb generation. We report design, fabrication, and characterization of devices in the 1550-nm wavelengths bands, including the GVD spectrum and quality factor. Moreover, we report Kerr-comb generation by exciting the devices with a continuous-wave laser. The versatility of PCRs enables a general design principle and a common device infrastructure for Kerr-nonlinear- resonator processes, opening new possibilities for manipulation of light. Visible and multi- spectral-band resonators appear to be natural extensions of the PCR approach.
