Provided are a technique and a device, which enable a laser to be locked and stabilized to an optical resonator through self-injection locking based on reflection feedback. An echo wall mode optical resonator is performed to provide light filtering and injection feedback based on the reflection ...
Herein, two narrow linewidth DFB lasers can be independently achieved by Rayleigh backscattering excited in a micro-resonator as feedback for self-injection locking. The 3-dB linewidth of the DFB laser is compressed from 320 kHz to 1.5 kHz, which is narrowed by 2 orders of magnitude. Based ...
摘要: We present the analysis of the self-injection locking of a single-frequency laser diode to a high-Q whispering gallery mode (WGM) microresonator with Rayleigh backscattering. Simple analytical formulas for the width of the locking band and resulting laser linewidth are derived....
We reported an integrated all-fiber 350Hz linewidth distributed feedback (DFB) fiber laser assisted by self- injection locking;Theoretically and experimentally verified the apodized π phase-shifted fiber Bragg grating (π-FBG) could achieve much better single longitudinal mode operation;We have encapsu...
We report experimental studies of a self-injection locking technique with optically filtered feedback and its influence on optical linewidth, RF linewidth, carrier side-band suppression and frequency stability of a monolithically integrated InP passive mode-locked laser. We use a Fabry-Perot etalon as...
BACKGROUND:Self-injection locking (SIL) radar uses continuous-wave radar and an injection-locked oscillator-based frequency discriminator that receives and demodulates radar signals remotely to monitor vital signs. This study aimed to compare SIL radar w

We report on experimental demonstration of a low-cost sub-kilohertz Brillouin fiber ring laser pumped from an actively stabilized self-injection locked distributed feedback (DFB) laser diode. Locking of the commercial DFB laser to a ~11-m-length high-Q-factor fiber-optic ring cavity leads to ...
The present study proposes and demonstrates a narrow-linewidth thulium-holmium co-doped fiber laser based on self-injection locking. The laser with single-longitudinal-mode operation is realized using a fiber Bragg grating as a wavelength-selection component and a dual-ring compound cavity as a ...
