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.

Influence of the microresonator nonlinearity on the self-injection locking effect [PDF]

EPJ Web of Conferences, 2019
The effect of self-injection locking of a laser to a nonlinear microresonator is considered. It is shown that an additional detuning arises in the system, depending on the pump power.

Passive Mode-Locking of Monolithic InGaAs/AlGaAs Double Quantum Well Lasers at 42GHz Repetition Rate [PDF]

, 1990
Pulse trains with a 42GHz repetition rate were generated by monolithic InGaAs/AlGaAs double quantum well lasers at a wavelength of 985 [angstroms]. The cavity was electrically divided into three regions, one providing gain and the other two providing ...

Self-injection-locked second-harmonic integrated source

, 2022
High coherence visible and near-visible laser sources are centrally important to the operation of advanced position/navigation/timing systems as well as classical/quantum sensing systems. However, the complexity and size of these bench-top lasers is an impediment to their transitioning beyond the laboratory.

Frequency-sweep generation by resonant self-injection locking

Optics Letters, 1999
We report a novel application of self-injection locking. A diode laser is injection locked to its own frequency-shifted emission. By resonant phase modulation of the fed-back light, the laser's emission frequency is shown to swing periodically through the locking range. The laser operates as a sweep generator driven by resonant self-injection locking.

Determining the Stable Injection Locking of a Fabry-Pérot Laser by Observing the RF Spectral Components Generated by a Low-Reflectivity External Cavity

Photonics, 2021
A novel approach to monitoring the laser injection-locking (IL) state is proposed and verified using the side-mode suppression ratio (SMSR). In a photonics experiment for laser IL, an optical spectrum analyzer with the conventional criterion of a 35-dB ...
