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 ...

Generation of dual and quad-optical frequency combs in the injected radiation free mode-locked frequency-shifted feedback laser [PDF]
Frontiers of Optoelectronics, 2023 The results of an optoelectronic system—frequency-shifted feedback (FSF) laser experimental examination are presented. The considered FSF laser is seeded only with optical amplifier spontaneous emission (ASE) and operates in the mode-locked regime ...

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.

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 ...

Optical frequency combs for optical fiber communications
APL PhotonicsOptical frequency combs are analyzed in the context of using them for carrying data in optical fiber communication systems. Combs are analyzed for their data-carrying capacity, i.e., for how much data they can carry, in massively multiplexed systems, and

Optical frequency combs generated by four-wave mixing in a dual wavelength Brillouin laser cavity
AIP Advances, 2017 We propose and demonstrate the generation of optical frequency combs via four-wave mixing in a dual wavelength Brillouin laser cavity. When pumped by two continuous-wave lasers with a varied frequency separation, dual wavelength Brillouin lasers with ...
