Abstract
Systems and methods for a self-injection locked SBS laser are provided herein. In certain embodiments, a system includes a pump laser source providing a pump laser; an SBS resonator receiving the pump laser through a first port and scattering some of the pump laser to provide an SBS laser through the first port, wherein a frequency shift of Brillouin scattering within the SBS resonator is an integer multiple of a free-spectral range for the SBS resonator; a filter receiving the pump laser on a first filter port and the SBS laser on a second filter port, wherein the pump laser is output through the second filter port and the SBS laser is output through a drop port; and a pump laser path coupling the output pump laser into the pump laser source, wherein a frequency of the pump laser becomes locked to a resonance frequency of the SBS resonator.
