Review of Self-Injection-Locked Radar Systems for Noncontact …
WebBy self-injection locking, the formed compound cavity extends the photon lifetime, which suppresses the amplified spontaneous emission (ASE) noise, narrowing the spectral linewidth and improving the coherent time. Coupling high-Q whispering gallery mode (WGM) microresonator to . distributed feedback (DFB) laser, it achieves sub-100 Hz linewidth ... WebSelf-injection locking to a WGM microresonator uses resonant Rayleigh scattering [22, 23] on internal and surface inhomogeneities when a fraction of incoming radiation in resonance with the frequency of the selected WGM reflects back to the laser. This e ect provides fast optical feedback and may result in a significant reduction of the laser phew smell

WebDec 16, 2024 · Self-injection locking is a dynamic phenomenon, which provides passive stabilization of a laser emission frequency via resonant optical feedback. The stabilization coefficient depends on the level of the feedback and quality factor of the external resonant structure creating the feedback.
