Kerr frequency comb-based K a -band RF photonic oscillator
Vladimir S. Ilchenko,Jerry Byrd,Anatoliy A. Savchenkov,Danny Eliyahu,Wei Liang,Andrey B. Matsko,David Seidel,Lute Maleki +7 more
TL;DR: In this paper, a packaged RF photonic oscillator based on Kerr optical frequency comb generated in an ultra-high Q crystalline whispering gallery mode (WGM) resonator is presented.
Proceedings ArticleDOI
Spectrally Pure RF Photonic Source Based on a Resonant Optical Hyper-Parametric Oscillator
TL;DR: In this article, the authors demonstrate a free running 10GHz microresonator-based RF photonic hyperparametric oscillator characterized with phase noise better than -60dBc/Hz at 10Hz, -90dBc /Hz at 100Hz, and -150dBc * at 10MHz.

Strongly Nondegenerate Resonant Optical Parametric Oscillator
Wei Liang,Anatoliy A. Savchenkov,James F. McMillan,Zhenda Xie,Vladimir S. Ilchenko,David Seidel,Chee Wei Wong,Andrey B. Matsko,Lute Maleki +8 more
TL;DR: In this article, the authors demonstrate a low-threshold, visible light, resonant OPO with widely separated harmonics, which is phase matched due to interaction of different mode families of the resonator.
