Self-injection locked phase-locked loop OEO
IEEE MTT-S International Microwave and RF Conference, 2013A novel optoelectronic oscillator (OED) circuit using self-injection locked phase-locked loop (SILPLL) technique is reported for high frequency stable ultra-low phase noise signal source applications.

Self-injection locked blue laser
Journal of Optics, 2018We demonstrate a 446.5 nm GaN semiconductor laser with sub-MHz linewidth. The linewidth reduction is achieved by locking the laser to a magnesium fluoride whispering gallery mode resonator characterized with 109 quality factor. Self-injection locking ensures single longitudinal mode operation of the laser.

Nonlinear Self-Injection Locking: Theory and Experiment
OSA Advanced Photonics Congress (AP) 2020 (IPR, NP, NOMA, Networks, PVLED, PSC, SPPCom, SOF), 2020The impact of microresonator nonlinearity on the self-injection locking is studied. The theoretical model is developed and confirmed experimentally using a DFB diode locked to a chip-based microresonator. Nontrivial dynamics is uncovered.

The self-injected nonmode-locked picosecond laser
IEEE Journal of Quantum Electronics, 1983A new type of laser which generates picosecond pulses is presented. 6 ps, ∼ 1 GW, 3 pps, \lambda = 1.06 \mu m in a single pulse are obtained with good stability. Accurate timing of the pulses can be achieved, and no external pulse selection is required.

Self-injection Locked Microcombs in Photonic Crystal Microresonators
CLEO 2023, 2023Self-injection locking to a photonic crystal ring-microresonator with tailored back-reflection is demonstrated for the first time. The chip-integrated system does not rely on random imperfection-based backscattering and permits deterministic and robust generation of single-soliton microcombs.

IEEE Transactions on Electron Devices, 2007
We report an experimental observation of frequency locking and noise reduction in a self-injection-locked magnetron oscillator operating at 2.455 GHz. Part of the magnetron output signal is injected into the magnetron through a feedback loop to lock the oscillation frequency.

Optimization of the self-injection locking and resonator characterisation in this regime
Laser Resonators, Microresonators, and Beam Control XXIII, 2021Self-injection locking (SIL) is an effect of the oscillator frequency stabilization by means of a passive external high-quality cavity enabling frequency filtered coherent optical feedback to the oscillator. It is widely used in various photonic applications, including compact narrow-linewidth lasers and microcomb sources.

Experimental study on self-injection-locking oscillator
Conference on Lasers and Electro-Optics Europe, 1994A new method to reduce divergence of copper vapor laser beam was developed successfully using double discharge. Divergence as small as a conventional injection locking oscillator system was obtained with the single bore unit.

Frequency Stability Enhancement of Self-Injection Locked Laser
Frontiers in Optics / Laser Science, 2020We developed a model that enables both a deeper understanding of the salient physical features of the self-injection locking of a laser to high-quality factor WGM microresonator and corresponding improvements of the laser frequency stabilization.
