Optical frequency comb spectroscopy
Faraday Discussions, 2011Optical frequency combs offer enormous potential in the detection and control of atoms and molecules by combining their vast spectral coverage with the extremely high spectral resolution of each individual comb component. Sensitive and multiplexed trace gas detection via cavity-enhanced direct frequency comb spectroscopy has been demonstrated for ...

Spectrometry with frequency combs
Optics Letters, 2002A method is proposed for performing accurate spectral characterization of samples with frequency combs, e.g., from mode-locked lasers, over the spectral range covered by the combs. The essence of the method is the use of two combs of slightly different mode spacing to achieve spectral resolution.

Nonlinear Optics, 2011
Frequency combs generated by Synchronously Pumped Parametric Oscillators exhibit nonclassical features such as multimode squeezing and multipartite entanglement that we have investigated experimentally and which can be used to improve time measurements beyond the shot noise limit.

Optica Sensing Congress 2023 (AIS, FTS, HISE, Sensors, ES), 2023
The structure of frequency combs, evenly-space light sources, allows for novel strategies in the measurement of optical signals. We discuss ptychoscopy, a method that blends the resolution of heterodyne spectroscopy with the bandwidth of combs.

Nature Physics, 2021
Light propagating in the topological edge channel of an array of ring resonators is predicted to generate nested frequency combs: like a Matryoshka doll containing a set of smaller dolls, each ‘tooth’ of the comb comprises another frequency comb.

SPIE Proceedings, 2010
While being the most precise measurement tool in physics, high precision laser spectroscopy is still limited to wavelengths in the range between the infrared and the near ultraviolet. The generation of XUV frequency combs might be a route to extend optical frequency metrology into extreme ultraviolet (XUV) spectral region where many elements have ...

Microresonator frequency combs
2013 Conference on Lasers & Electro-Optics Europe & International Quantum Electronics Conference CLEO EUROPE/IQEC, 2013Femtosecond-laser frequency combs have revolutionized optical frequency metrology and precision timekeeping by providing a dense set of absolute reference lines that can span in excess of an octave. Beyond their natural application as an optical clockwork [1], frequency combs are used in diverse applications including measurements of fundamental ...

Asymmetric Magnon Frequency Comb
Nano LettersWe theoretically show the asymmetric spin wave transmission in a coupled waveguide-skyrmion structure, where the skyrmion acts as an effective nanocavity allowing the whispering gallery modes for magnons. The asymmetry originates from the chiral spin wave mode localized in the circular skyrmion wall. By inputting two-tone excitations and mixing them in

Science, 2016
Quantum Optics The ability to generate optical frequency combs in which the output light is made up of millions of sharp lines precisely spaced apart has been important for optical applications and for fundamental science. Reimer et al. now show that frequency combs can be taken into the quantum regime.
