Quadratic Optical Frequency Combs [PDF]
2019 IEEE Photonics Conference (IPC), 2019 Optical frequency comb sources based on quadratic nonlinearities provide an interesting alternative to Kerr combs in terms of reduced pump power requirements and extended spectral coverage. We review theory and recent experiments of quadratic optical frequency combs based on second-harmonic generation and optical parametric oscillation.

Interferometry with optical frequency combs
Photoniques, 2022 A frequency comb, a spectrum of equidistant phase-coherent laser lines, can be harnessed for new approaches to interferometry. The dual-comb interferometer exploits the time-domain interference between two combs of slightly different line spacing. The instrument, which performs direct frequency measurements over a broad spectral bandwidth, opens up new

Femtosecond Optical Frequency Combs [PDF]
The European Physical Journal Special Topics, 2009 A laser frequency comb allows the conversion of the very rapid oscillations of visible light of some 100’s of THz down to frequencies that can be handled with conventional electronics. This capability has enabled the most precise laser spectroscopy experiments yet that allowed to test quantum electrodynamics, to determine fundamental constants and to ...

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
