We demonstrate comprehensive investigation of the injection locking dynamics of a backscattered Brillouin laser in silica whispering-gallery-mode microcavity.Via injection locking,the Brillouin laser acquires highly correlated phase with the seed laser,enabling ultra-narrow bandwidth,high gain,and coherent optical amplification.Also,for the first time,to the best of our knowledge,the injection locked Brillouin laser is utilized to implement all-optical carrier recovery from coherent optical data signals.We show that by using the injection locked Brillouin laser as a local oscillator for self-homodyne detection,high-quality data receiving can be realized,even without traditional electrical compensations for carrier frequency and phase drifts.
