All Year All A chip-scale second-harmonic source via self-injection-locked all-optical poling We present a chip-scale second-harmonic source based on the self-injection-locking of a semiconductor laser to a high-Q silicon nitride microresonator. All-optical poling enables efficient frequency conversion with hertz-level emission linewidth.
