Characterization of Silicon Whispering Gallery Mode Resonator Using Self-Injection Locking Regime

Abstract

We observed the self-injection locking of DFB diode laser to whispering gallery mode resonator in the mid-IR. Theory of the self-injection locking was proved to be sufficient for describing experimental results. We proposed the technique of determination in the self-injection locking regime parameters of the whispering gallery mode resonator that are important and hard to measure in such case.
