光子集成器件以极低的成本和功耗实现覆盖从光源、调制、非线性频率转换、光放大到光探测的全功能单片集成,对光电信息处理系统产生显著而深远的影响,并推动一系列诸如高速通信、人工智能、量子信息,以及精密测量等重大应用领域的持续发展。近年来,铌酸锂薄膜光子器件得益于离子揭膜技术和微纳刻蚀工艺的进步,以宽的工作窗口、低的传输损耗、大的调制带宽、高的非线性光学转换效率和兼容大规模光子集成等优点,在集成光子学领域占据重要一席之地。本文介绍了利用超快激光光刻结合化学机械抛光技术在掺杂有源发光稀土离子的铌酸锂薄膜衬底上实现片上激光与光放大的最新进展,包括在波导放大器中实现了超过20 dB的最大内部净增益,并且在高品质铌酸锂微盘中演示了具有454.7 Hz窄线宽的电光可调谐单频激光器,演示了单片集成的电驱动微环激光器,以及连续光刻方式实现的无源/有源混合集成器件。

We report an electro-optically (EO) tunable microdisk laser fabricated on the erbium (Er3+)-doped lithium niobate on insulator (LNOI) substrate. By applying a variable voltage on a pair of integrated chromium (Cr) microelectrodes fabricated near the LNOI microdisk, electro-optic modulation with an effective resonance-frequency tuning rate of 2.6 GHz/100 V has been achieved. This gives rise to a tuning range of 45 pm when the electric voltage is varied between -200 V and 200 V.

We demonstrate high-quality (intrinsic Q factor ∼2.8 × 106) racetrack microresonators fabricated on lithium niobate thin film with a free spectral range (FSR) of ∼86 pm. By integrating microelectrodes alongside the two straight arms of the racetrack resonator, the resonance wavelength around 1550 nm can be red shifted by 92 pm when the electric voltage is raised from -100 V to 100 V. The microresonators with the tuning range spanning over a full FSR are fabricated using photolithography assisted chemo-mechanical etching.
