Journal ArticleDOI
High spectral purity Kerr frequency comb radio frequency photonic oscillator
Wei Liang,Danny Eliyahu,Vladimir Ilchenko,Anatoliy A. Savchenkov,Andrey B. Matsko,David Seidel,Lute Maleki +6 more
TL;DR: This work demonstrates a miniature 10 GHz radio frequency photonic oscillator characterized with phase noise better than −60 dBc Hz−1 at 10GHz, −90 dBcHz+1 at 100MHz, and −170dBC Frequency Stability, at the level of 10−10 at 1–100s integration time.
Journal ArticleDOI
Probing 10 μK stability and residual drifts in the cross-polarized dual-mode stabilization of single-crystal ultrahigh- Q optical resonators
TL;DR: In this article, the authors investigated the correlation between the dual-mode beat frequency and the resonator temperature with time and the associated spectral noise of the dual mode beat frequency in a single-crystal ultrahigh-Q MgF2 resonator.
Journal ArticleDOI
Ultralow noise miniature external cavity semiconductor laser
Wei Liang,Vladimir Ilchenko,Danny Eliyahu,Anatoliy A. Savchenkov,Andrey B. Matsko,David Seidel,L. Maleki +6 more
TL;DR: This work reports on a realization of a heterogeneously integrated, chip-scale semiconductor laser featuring 30-Hz integral linewidth as well as sub-Hz instantaneous linewaith in advanced applications in optical metrology.
Journal ArticleDOI
Whispering-gallery-mode-resonator-based ultranarrow linewidth external-cavity semiconductor laser
TL;DR: A miniature self-injection locked distributed-feedback laser using resonant optical feedback from a high-Q crystalline whispering-gallery-mode resonator that possesses excellent spectral purity and good long-term stability is demonstrated.
Journal ArticleDOI
Mode-locked Kerr frequency combs.
Andrey B. Matsko,Anatoliy A. Savchenkov,Wei Liang,Vladimir Ilchenko,David Seidel,Lute Maleki +5 more
TL;DR: Using damped driven nonlinear Schrödinger equations, it is shown that the combs can produce subpicosecond optical pulses when the resonators are characterized with a small enough anomalous group velocity dispersion.
