2023-12-08 Laser diode-pumped compact hybrid lithium niobate microring laser doi:10.57760/sciencedb.14069 en We demonstrate a compact hybrid lithium niobate microring laser by butt coupling a commercial 980-nm pump laser diode chip with a high-quality Er 3+ -doped lithium niobate microring chip. Single-mode lasing emission at 1531-nm wavelength from the Er 3+ -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 mm ×4 mm ×0.5 mm. The threshold pumping laser power is 6 mW and the threshold current is 0.5 A (operating voltage 1.64 V) at 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.  lithium niobate; microring laser; diode chip Junxia Zhou Ting Huang Zhiwei Fang Rongbo Wu Yuan Zhou Jian Liu Haisu Zhang Zhenhua Wang Min Wang Ya Cheng PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset Science Data Bank
