Integrated multi-color Raman microlasers with ultra-low pump levels in single high-Q lithium niobate microdisks
Guanghui Zhao, Jintian Lin, Botao Fu +8
Photonic integrated Raman microlasers, particularly discrete multi-color lasers which are crucial for extending the emission wavelength range of chip-scale laser sources to much sh…
Erbium-ytterbium co-doped lithium niobate single-mode microdisk laser with an ultralow threshold of 1 uW
Minghui Li, Renhong Gao, Chuntao Li +9
We demonstrate single-mode microdisk lasers in the telecom band with ultra-low thresholds on erbium-ytterbium co-doped thin-film lithium niobate (TFLN). The active microdisk were f…
Generation of Kerr soliton microcomb in a normally dispersed lithium niobate microdisk resonator by mode trimming
Botao Fu, Renhong Gao, Ni Yao +6
Anomalous microresonator dispersion is mandatory for Kerr soliton microcomb formation, which depends critically on the geometry of the microresonator and can hardly be tuned after…
Ultra-high Q lithium niobate microring monolithically fabricated by photolithography assisted chemo-mechanical etching
Chuntao Li, Jianglin Guan, Jintian Lin +5
Thin-film lithium niobate (TFLN) has been considered as one of the most important platforms for constructing high-performance photonic integrated devices such as electro-optic modu…
Multi-mode Perturbation Modelling for Cavity Polygon and Star Modes
Saeed Farajollahi, Zhiwei Fang, Jintian Lin +3
Polygon and star modes enable unidirectional emission and single-frequency lasing in whispering gallery microcavities. To understand their properties and facilitate design, we have…
