    Abstract

    We report the first observation of low power drive level sensitivity, hyperparametric amplification,and single-mode hyperparametric oscillations in a dielectric rutile whispering-gallery mode resonator at 4.2K. The latter gives rise to a comb of sidebands at 19.756GHz. Whereas, most frequency combs in the literature have been observed in optical systems using an ensemble of equally spaced modes in microresonators or fibers, the present work represents generation of a frequency comb using only a single-mode. The experimental observations are explained by an additional 1/2 degree-of-freedom originating from an intrinsic material nonlinearity at optical frequencies, which affects the microwave properties due to the extremely low loss of rutile. Using a model based on lumped circuits, we demonstrate that the resonance between the photonic and material 1/2 degree-of-freedom, is responsible for the hyperparametric energy transfer in the system. © 2014 AIP Publishing LLC
