Photonic Generation of Millimeter-Waves Disciplined by Molecular Rotational Spectroscopy

James Greenberg, Rubab Amin, Brendan M. Heffernan +1

Optical generation of millimeter-waves (mm-wave) is made possible by an optical heterodyne of two diode lasers on a uni-traveling-carrier photodiode (UTC-PD). We utilized this tech…

Effects of a quiet point on a Kerr microresonator frequency comb

Tomohiro Tetsumoto, Jie Jiang, Martin E. Fermann +3

A quiet point, an operating point of pump-resonance detuning that minimizes frequency fluctuation due to nonlinear effects inside a resonator, has been employed for phase noise red…
