Isotropic fabrication of centimeter-scale, low propagation-loss periodically poled lithium niobate nanophotonic waveguides for efficient second harmonic generation
Guanghui Zhao, Yixuan Yang, Renhong Gao +2
Periodically poled lithium niobate (PPLN) nanophotonic waveguides that simultaneously feature low propagation-loss and uniform periodic poling are essential for a wide range of app…
Simultaneous generation of Raman-assisted Soliton Microcombs and Tunable Multi-chromatic Raman Microlasers in Single Monolithic Thin-film Lithium Niobate Microrings
Yingnuo Qiu, Renhong Gao, Chuntao Li +9
High-performance integrated broadband coherent light sources are essential for advanced applications in high-bandwidth data processing and chip-scale metrology, yet remain challeng…
Low-loss thin-film periodically poled lithium niobate waveguides fabricated by femtosecond laser photolithography
Guanghui Zhao, Jintian Lin, Renhong Gao +10
Periodically poled lithium niobate on insulator (PPLNOI) ridge waveguides are critical photonic components for both classical and quantum information processing. However, dry etchi…
Frequency stabilization based on H13C14N absorption in lithium niobate micro-disk laser
Zhen Yi, Zhihao Zhang, Jianglin Guan +8
We demonstrate an on-chip lithium niobate micro-disk laser based on hydrogen cyanide (H13C14N) gas saturation absorption method for frequency stabilization. The laser chip consists…
