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 ...

Synthetic Self-injection Locked Microcombs for Deterministic Single Soliton Operation [PDF]
EPJ Web of Conferences, 2023 Self-injection locking to a photonic crystal ring-microresonator with synthetic back-reflection is demonstrated for the first time. The on-chip system permits deterministic generation of exclusively single-soliton microcombs and does not rely on random ...

Dual-laser self-injection locking to an integrated microresonator
Optics Express, 2022 Diode laser self-injection locking (SIL) to a whispering gallery mode of a high quality factor resonator is a widely used method for laser linewidth narrowing and high-frequency noise suppression. SIL has already been used for the demonstration of ultra-low-noise photonic microwave oscillators and soliton microcomb generation and has a wide range of ...

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.

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‐
