Nonlinear optics and crystalline whispering gallery mode resonators

摘要

We report on our recent results concerning fabrication of high-Q whispering gallery mode (WGM) crystalline resonators, and discuss some possible applications of lithium niobate WGM resonators in nonlinear optics and photonics. In particular, we demonstrate experimentally a tunable third-order optical filter-fabricated from the three metalized resonators; and report observation of parametric frequency doubling in a WGM resonator made of periodically poled lithium niobate (PPLN).
