WebJun 9, 2024 · Self-injection locking is a dynamic phenomenon representing stabilization of the emission frequency of an oscillator with a passive cavity enabling frequency filtered coherent feedback to the oscillator cavity. WebJun 24, 2024 · Self-injection locking is used over many years in radio physics and microwave electronics to stabilize devices and improve their spectral purity [30–33]. In the past decades, the self-injection locking effect was also widely applied in optics and laser physics [34–44]. The most interesting results were obtained for WGM microresonators …
WebJan 1, 2016 · Self-injection locking is an efficient technique used to improve the spectral and polarization performance of semiconductor lasers attractive for many applications in optical communication and sensing [1], [2]. 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
