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 ...

Multi-Mode Lasers for Self-Forced Opto-Electronic Oscillators in Compact Frequency Synthesizers
IEEE Journal of Microwaves, 2021 Advanced telecommunication, imaging, and remote sensing systems require reliable ultra-high stability local oscillators. Particularly, coherent detection of digital data signals relies on a low aperture jitter of local oscillators in addition to high ...

Generation of frequency combs and dissipative solitons in integrated microresonators in self-injection locking regime [PDF]
EPJ Web of Conferences, 2019 We developed a method to generate frequency combs that implements compact multimode diode laser. This technique allows for generating of low-noise frequency combs with the linewidth around 100 kHz due to self-injection locking effect.
