Dielectric perturbations: anomalous resonance frequency shifts in optical resonators
Farhan Azeem, Luke S. Trainor, Patrick A. Devane +6
Small perturbations in the dielectric environment around a high quality whispering gallery mode resonator usually lead to a frequency shift of the resonator modes directly proporti…
Experimental observation of internally-pumped parametric oscillation and quadratic comb generation in a whispering-gallery-mode microresonator
Ian Hendry, Luke S. Trainor, Yiqing Xu +4
We report on the experimental observation of internally-pumped parametric oscillation in a high-Q lithium niobate microresonator under conditions of natural phase-matching. Specifi…
Octave-spanning tunable parametric oscillation in crystalline Kerr microresonators
Noel Lito B. Sayson, Toby Bi, Vincent Ng +6
Parametric nonlinear optical processes allow for the generation of new wavelengths of coherent electromagnetic radiation. Their ability to create radiation that is widely tunable i…
Origins of clustered frequency combs in Kerr microresonators
Noel Lito B. Sayson, Hoan Pham, Karen E. Webb +6
Recent experiments have demonstrated the generation of widely-spaced parametric sidebands that can evolve into "clustered" optical frequency combs in Kerr microresonators. Here we…
