Ultrafast tunable lasers using lithium niobate integrated photonics.

ABSTRACT: Early works¹ and recent advances in thin-film lithium niobate (LiNbO₃) on insulator have enabled low-loss photonic integrated circuits^2,3, modulators with improved half-wave voltage^4,5, electro-optic frequency combs⁶ and on-chip electro-optic devices, with applications ranging from microwave photonics to microwave-to-optical quantum interfaces⁷. Although recent advances have demonstrated tunable integrated lasers based on LiNbO₃ (refs. ^8,9), the full potential of this platform to demonstrate frequency-agile, narrow-linewidth integrated lasers has not been achieved. Here we report such a laser with a fast tuning rate based on a hybrid silicon nitride (Si₃N₄)-LiNbO₃ photon
