Abstract

Chip-scale mode-locked dissipative Kerr solitons have been realized on various materials platforms, making it possible to achieve a miniature, highly coherent frequency comb source with high repetition rates. Aluminum nitride (AlN), an appealing nonlinear optical material having both Kerr (𝜒3) and Pockels (𝜒2) effects, has immerse potential for comb self-referencing without the need for external harmonic generators. Here we demonstrate deterministic Kerr cavity soliton generation in crystalline AlN microring resonators. By utilizing phase matched waveguides, we further show the extension of a Kerr comb to the UV band.
