Synthetic Self-injection Locked Microcombs for Deterministic Single Soliton Operation
Abstract
Self-injection locking to a photonic crystal ring-microresonator with synthetic back-reflection is demonstrated for the first time. The on-chip system permits deterministic generation of exclusively single-soliton microcombs and does not rely on random backscattering from defects or imperfections.
