Dynamics of the Frequency Shifts in Semiconductor Lasers under the Injection of a Frequency Comb

Photonics, 2022
We have numerically investigated the dynamics of frequency shifts in semiconductor lasers under the injection of a frequency comb. We have studied the effect of comb spacing on the locking bandwidth.

Frequency pushing and pulling in semiconductor lasers subject to optical frequency comb injection

Results in Engineering
We 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

Frequency comb ptychoscopy

Nature Communications, 2021
Multiheterodyne techniques using frequency combs—radiation sources whose lines are perfectly evenly-spaced—have revolutionized science. By beating sources with the many lines of a comb, their spectra are recovered.

Single-cycle all-fiber frequency comb

APL Photonics, 2021
Single-cycle pulses with a deterministic carrier-envelope phase enable the study and control of light–matter interactions at the sub-cycle timescale, as well as the efficient generation of low-noise multi-octave frequency combs.

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.
