论文摘要
我们通过对接偶联的980 nm泵激光二极管芯片与高质量的ER3+掺杂的Niobate微林芯片偶联，证明了电动驱动的紧凑型杂化型尼伯特微酸酯激光器。可以通过集成的980 nm激光泵泵观察到ER3+掺杂的Niobate微林的1531 nm波长下的单模式激光发射。紧凑型混合锂硅硅晶微林激光占3 mmx4mmx0.5 mm的芯片尺寸。阈值泵送激光功率为6兆瓦，在大气温度下的阈值电流为0.5 a（操作电压1.64 V）。观察到具有单个模式激光的光谱，小线宽为0.05 nm。这项工作探讨了强大的杂种尼橙酸锂微林激光源，该激光源在连贯的光学通信和精度计量学中具有潜在的应用。
We demonstrate an electrically driven compact hybrid lithium niobate microring laser by butt coupling a commercial 980-nm pump laser diode chip with a high quality Er3+-doped lithium niobate microring chip. Single mode lasing emission at 1531 nm wavelength from the Er3+-doped lithium niobate microring can be observed with the integrated 980-nm laser pumping. The compact hybrid lithium niobate microring laser occupies the chip size of 3 mmx4mmx0.5 mm. The threshold pumping laser power is 6 mW and the threshold current is 0.5 A (operating voltage 1.64 V) in the atmospheric temperature. The spectrum featuring single mode lasing with small linewidth of 0.05 nm is observed. This work explores a robust hybrid lithium niobate microring laser source which has potential applications in coherent optical communication and precision metrology.
