摘要

混合集成自注入锁定（SIL）激光器为片上窄线宽光源提供了一个很有前途的解决方案，但它们无法同时满足窄线宽和高功率要求，限制了实际应用。我们展示了一种混合集成的电光可调谐窄线宽SIL激光器，其输出功率为7.6 mW，本征线宽为717 kHz。外腔由加滴微环和Sagnac环反射器构成。利用铌酸锂的高电光效率，实现了0.62 pm/V的调谐效率。这项工作为紧凑、低成本、高功率、窄线宽的片上激光器铺平了道路。

Hybrid-integrated high-power electro-optically tunable self-injection-locked laser

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.
