Optical Frequency Comb Generation based on Erbium Fiber Lasers
Nanophotonics, 2016 Optical frequency combs have revolutionized optical frequency metrology and are being actively investigated in a number of applications outside of pure optical frequency metrology. For reasons of cost, robustness, performance, and flexibility, the erbium

Frequency pushing and pulling in semiconductor lasers subject to optical frequency comb injection
Results in EngineeringWe theoretically investigate the frequency shift of a free-running semiconductor laser when optically injected by an optical frequency comb. By numerical integration of the laser rate equations, we have identified two types of frequency shifts, frequency

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.

Chip-based optical frequency combs for high-capacity optical communications
Nanophotonics, 2021 Current fibre optic communication systems owe their high-capacity abilities to the wavelength-division multiplexing (WDM) technique, which combines data channels running on different wavelengths, and most often requires many individual lasers.

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 ...
