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

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

Acoustic frequency combs using gas bubble cluster oscillations in liquids: a proof of concept
Scientific Reports, 2021 We propose a new approach to the generation of acoustic frequency combs (AFC)—signals with spectra containing equidistant coherent peaks. AFCs are essential for a number of sensing and measurement applications, where the established technology of optical
