Monolithic tantalum pentoxide microrings with intrinsic Q factors exceeding 4X10(6)
Xinzhi Zheng, Yixuan Yang, Renhong Gao +3
Tantalum pentoxide (Ta2O5), as a silicon-photonic-compatible material platform, has garnered significant attention for high-performance integrated photonics due to its exceptional…
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…
2.7-octave supercontinuum generation spanning from ultraviolet to near-infrared in thin-film lithium niobate waveguides
Minghui Li, Qiankun Li, Yongyuan Chu +7
Supercontinuum generation (SCG) with spectral coverage across the full visible and ultraviolet (UV) ranges is crucial for optical clocks, quantum computing and sensing. However, ac…
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…
Second harmonic generation with 48% conversion efficiency from cavity polygon modes in a monocrystalline lithium niobate microdisk resonator
Chao Sun, Jielei Ni, Chuntao Li +10
Thin-film lithium niobate (TFLN) based optical microresonators offer large nonlinear coefficient d_33 and high light-wave confinement, allowing highly efficient second-order optica…
