Abstract

Recent works have demonstrated how silicon nitride integrated photonics can be endowed with photoinduced second-order nonlinearities for efficient frequency conversion. Here we will showcase how highly-efficient second-harmonic generation in a microresonator can be combined with self-injection locking to a DFB laser to create a standalone dual-wavelength displaying high output power, conversion efficiency and hertz-level coherence in an integrated fashion. We will also cover how the photoinduced nonlinearity can trigger cascaded effects, expanding the operation range and functionality of the microresonator, and discuss how silicon nitride microrings can be further mode engineered to provide combined high efficiency and wide tunability of the nonlinear processes.
