We demonstrate a monolithic tunable dual-wavelength laser fabricated on erbium-doped lithium niobate on an insulator (Er:LNOI). The dual-wavelength laser enables independent tuning with a continuously linear electro-optic (EO)-modulated tuning range of 11.875 GHz at a tuning efficiency of 0.63 pm/V. Tunable microwave generation within 50 GHz with a maximum extinction ratio of 35 dB is experimentally demonstrated by further exploring the charge accumulation effect in LNOI. The monolithic design of this work paves the way for microscale integration of laser devices, presenting significant prospects in photonics research and applications.
我们展示了一种在绝缘体上的掺铒铌酸锂（Er:LNOI）上制造的单片可调谐双波长激光器。该双波长激光器能够独立调谐，在0.63 pm/V的调谐效率下，具有11.875 GHz的连续线性电光（EO）调制调谐范围。通过进一步探索LNOI中的电荷积累效应，实验证明了在50 GHz范围内可调谐微波产生，最大消光比为35 dB。这项工作的单片设计为激光器件的微尺度集成铺平了道路，在光子学研究和应用中展现出显著的前景。
