Dielectric perturbations: anomalous resonance frequency shifts in optical resonators

Small perturbations in the dielectric environment around resonant dielectric structures usually lead to a frequency shift of the resonator modes directly proportional to the polarizability of the perturbation. Here, we report experimental …

Experimental observation of internally pumped parametric oscillation and quadratic comb generation in a χ^(2) whispering-gallery-mode microresonator

We report on the experimental observation of internally pumped parametric oscillation in a high-Q lithium niobate microresonator under conditions of natural phase matching. Specifically, launching near-infrared pump light around 1060 nm into a z-cut …
