TL;DR
This paper presents a theoretical explanation and experimental demonstration of high-contrast Kerr frequency combs with suppressed pump harmonic, achieved using a MgF2 resonator with reduced mode density and add-drop couplers.
Contribution
It introduces a novel resonator configuration that suppresses the pump harmonic in Kerr frequency combs, enhancing their contrast and potential applications.
Findings
Successful experimental demonstration of high-contrast combs
Theoretical model explaining harmonic suppression
Use of MgF2 resonator with reduced mode density
Abstract
Kerr frequency combs with depressed harmonic at the optical pump frequency are theoretically explained and experimentally demonstrated. This result is achieved in a MgF photonic belt resonator having reduced density of modes in its spectrum and configured with the add-drop optical couplers. \copyright 2016 California Institute of Technology.
