Parametric oscillations in a whispering gallery resonator

Opt Lett. 2007 Jan 15;32(2):157-9. doi: 10.1364/ol.32.000157.

Abstract

We demonstrate strongly nondegenerate optical continuous-wave parametric oscillations in crystalline whispering gallery mode resonators fabricated from LiNbO3. The required phase matching is achieved by geometrical confinement of the modes in the resonator.
