Mutual optical injection locking dynamics between a terahertz single-mode laser and a frequency comb laser [PDF]

APL Photonics
Frequency combs are powerful tools for precision metrology, spectroscopy, and communications. In the terahertz (THz) domain, the quantum cascade laser (QCL) offers an on-chip platform for self-started comb generation via four-wave mixing.

Optical pump assisted broadband terahertz frequency comb

AIP Advances, 2021
A broadband terahertz (THz) frequency comb assisted by an optical pump in THz quantum cascade lasers (QCLs) is investigated theoretically and numerically through a Maxwell–Bloch model combined with the coupled wave theory.

Optimization of acousto-optic optical frequency combs

Optics Express, 2019
Acousto-optic optical frequency combs can easily produce several hundreds of mutually coherent lines from a single laser, by successive frequency shifts in a loop containing an acousto-optic frequency shifter. They combine many advantages for multi-heterodyne interferometry and dual-comb spectroscopy.

Towards generation of optical frequency comb in the short-wavelength visible region using periodically poled lithium niobate waveguides

Results in Optics, 2021
We demonstrate the spectral broadening of an octave-spanning erbium-based frequency comb in two types of periodically poled lithium niobate (PPLN) waveguides.

Optical Frequency Combs Generated by Acousto-Optic Frequency-Shifting Loops [PDF]

IEEE Photonics Technology Letters, 2019
A recirculating loop that includes an acousto-optic frequency shifter (AOFS) constitutes a versatile procedure to generate an optical frequency comb (OFC) from a continuous wave (cw) laser. This scheme, implementable with conventional fiber equipment, is capable of producing spectra composed of at least hundreds of coherent lines using a single-stage ...

Frequency-comb-induced radiation pressure force in dense atomic clouds

, 2021
We investigate the frequency comb induced radiation pressure force acting on a cloud of cold $^{87}$Rb atoms. Reduction and spectral broadening of the frequency comb force are observed as the cloud's optical thickness is increased.

Controllable Kerr and Raman-Kerr frequency combs in functionalized microsphere resonators

Nanophotonics, 2019
Optical frequency comb (OFC) based on the whispering-gallery-mode microresonator has various potential applications in fundamental and applied areas. Once the solid microresonator is fabricated, its structure parameters are generally unchanged. Therefore,

Control of Frequency Combs with Passive Resonators

Sensors, 2023
Tailored optical frequency combs are generated by nesting passive etalons within mode-locked oscillators. In this work, the oscillator generates a comb of 6.8 GHz with 106 MHz side-bands.

Microresonator frequency comb optical clock

Optica, 2014
Optical-frequency combs enable measurement precision at the 20th digit, and accuracy entirely commensurate with their reference oscillator. A new direction in experiments is the creation of ultracompact frequency combs by way of nonlinear parametric optics in microresonators.
