Abstract

Hybrid-integrated self-injection locked (SIL) lasers offers a promising solution for on-chip narrow-linewidth light sources, their inability to simultaneously satisfy both narrow-linewidth and high-power requirements constrains practical applications. We demonstrate a hybrid-integrated electro-optically tunable narrow-linewidth SIL laser with an output power of 7.6 mW and an intrinsic linewidth of 717 kHz. The external cavity is constructed with an add-drop microring and a Sagnac loop reflector. Benefitting from the high electro-optic efficiency of lithium niobate, the tuning efficiency of 0.62 pm/V was achieved. This work paves the way for compact, low-cost, high-power, narrow-linewidth on-chip lasers.
