Self‐Injection Locked Frequency Conversion Laser
Laser & Photonics Reviews, 2023 AbstractHigh‐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 are an impediment to their transition beyond the laboratory. Here, a system‐on‐chip that emits high‐

Tunable self-injection locked green laser diode [PDF]
Optics Letters, 2018 We report, to the best of our knowledge, the first employment of a self-injection locking scheme for the demonstration of a tunable InGaN/GaN semiconductor laser diode. We have achieved a 7.11 nm (521.10-528.21 nm) tunability in a green color with different injection currents and temperatures.

Linewidth narrowing in self-injection-locked on-chip lasers [PDF]
Light: Science & Applications, 2023 Abstract Stable laser emission with narrow linewidth is of critical importance in many applications, including coherent communications, LIDAR, and remote sensing. In this work, the physics underlying spectral narrowing of self-injection-locked on-chip lasers to Hz-level lasing linewidth is investigated using a composite-cavity ...

Self-injection locking of the DFB laser through an external ring fiber cavity: Polarization behavior
Results in Physics, 2016 We study stability of self-injection locking realized with DFB laser coupled with an external fiber optic ring cavity. Polarization behavior of the radiation circulating in the feedback loop is reported.
