Low-threshold optical hyperparametric oscillations in a high-Q fluorite whispering gallery mode resonator are observed and it is demonstrated that, because of the narrow bandwidth of the resonator modes as well as the high efficiency of the resonate frequency conversion, the oscillations produce stable narrow-band beat-note of the pump, signal, and idler waves.
Tunable delay line with interacting whispering-gallery-mode resonators.
A parallel configuration of two interacting whispering-gallery-mode optical resonators is theoretically studied and a narrowband modal structure is shown as a basis for a widely tunable delay line.
Converting light into spectrally pure microwave oscillation.
This optoelectronic oscillator can generate ultrastable spectrally pure microwave reference frequencies as high as 75 GHz with a phase noise lower than 2140 dBcyHz at 10 kHz, independent of oscillation frequency.
