Resonant electro-optic frequency comb [PDF]

Nature, 2019
High speed optical telecommunication is enabled by wavelength division multiplexing, whereby hundreds of individually stabilized lasers encode the information within a single mode optical fiber. In the seek for larger bandwidth the optical power sent into the fiber is limited by optical non-linearities within the fiber and energy consumption of the ...

Theory of quadratic optical frequency combs [PDF]

2016 18th International Conference on Transparent Optical Networks (ICTON), 2016
We present theoretical studies of optical frequency comb generation in dispersive quadratically nonlinear resonators. We introduce a mean field equation approach to model cavity enhanced second harmonic generation and find excellent agreement with recent experimental frequency comb observations. We also develop a more general approach based on a single

Synchronization of frequency combs by optical injection

Optics Express, 2022
Optical frequency combs based on semiconductor lasers are a promising technology for monolithic integration of dual-comb spectrometers. However, the stabilization of offset frequency f ceo remains a challenging feat due the lack of octave-spanning spectra.

Dissipation Assisted Frequency Comb and Chaos Generation in the Optomechanics

IEEE Photonics Journal, 2022
Dispersion and dissipation are the key parameters of the optical components. Generally, dissipation is an unfavorable factor. In this article, we designed a dispersion-dissipation hybird coupling optomechanical cavity and achieved dissipation-assisted ...

Optical Frequency Combs in Quadratically Nonlinear Resonators [PDF]

Micromachines, 2020
Optical frequency combs are one of the most remarkable inventions in recent decades. Originally conceived as the spectral counterpart of the train of short pulses emitted by mode-locked lasers, frequency combs have also been subsequently generated in continuously pumped microresonators, through third-order parametric processes.
