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 …
