Abstract
A photonic device includes a substrate and a tantala ring resonator on the substrate. The tantala ring resonator has at least one of (i) a quality factor exceeding three million and (ii) a threshold power less than one hundred milliwatts. A frequency-comb generation method includes sweeping the output frequency of a laser coupled to a tantala ring resonator that has at least one of (i) a quality factor exceeding three million and (ii) a threshold power less than one hundred milliwatts.
Claims18
A photonic device, comprising:
- a substrate;
- and
- a tantala ring resonator formed on the substrate and having at least one of (i) an internal quality factor exceeding three million and (ii) a threshold power for parametric oscillation that is less than 100 mW.
A frequency-comb generation method, comprising:
- sweeping the frequency of a laser having a laser output that is coupled into a tantala ring resonator, the tantala ring resonator having at least one of (i) an internal quality factor exceeding three million and (ii) a threshold power for parametric oscillation that is less than 100 mW.
