Modes trimming and clustering in a weakly perturbed high-Q whispering gallery microresonator
Botao Fu, Renhong Gao, Jintian Lin +6
In general, a high-Q microresonator can accommodate abundant whispering gallery modes (WGMs) with the mode number increasing with the dimensional sizes of the microresonator. Remov…
Electro-optically tunable low phase-noise microwave synthesizer in an active lithium niobate microdisk
Renhong Gao, Botao Fu, Ni Yao +7
Photonic-based low-phase-noise microwave generation with real-time frequency tuning is crucial for a broad spectrum of subjects, including next-generation wireless communications,…
Monolithically integrated active passive waveguide array fabricated on thin film lithium niobate using a single continuous photolithography process
Yuan Zhou, Yiran Zhu, Zhiwei Fang +13
We demonstrate a robust low-loss optical interface by tiling passive (i.e., without doping of active ions) thin film lithium niobate (TFLN) and active (i.e., doped with rare earth…
On-chip integrated Yb3+-doped waveguide amplifiers on thin film lithium niobate
Zhihao Zhang, Zhiwei Fang, Junxia Zhou +10
We report the fabrication and optical characterization of Yb3+-doped waveguide amplifiers (YDWA) on the thin film lithium niobate fabricated by photolithography assisted chemo-mech…
Monolithically integrated waveguide-coupled single-frequency microlaser on erbium-doped thin film lithium niobate
Youting Liang, Junxia Zhou, Rongbo Wu +10
We overcome the difficulty in realizing a monolithic waveguide-coupled microring laser integrated on erbium-doped thin film lithium niobate (Er: TFLN) using photolithography assist…
Coherent mode-combined ultra-narrow-linewidth single-mode micro-disk laser
Jintian Lin, Saeed Farajollahi, Zhiwei Fang +10
Integrated single-mode microlasers with ultra-narrow linewidths play a game-changing role in a broad spectrum of applications ranging from coherent communication and LIDAR to metro…
