Low-loss Lithium Niobate on Insulator (LNOI) Waveguides of a 10 cm-length and a Sub-nanometer Surface Roughness
Rongbo Wu, Min Wang, Jian Xu +9
We develop a technique for realizing lithium niobate on insulator (LNOI) waveguides of a multi-centimeter-length with a propagation loss as low as 0.027 dB/cm. Our technique relies…
Highly-efficient second and third harmonic generation in a monocrystalline lithium niobate microresonator
Jintian Lin, Yao Ni, Zhenzhong Hao +10
Nonlinear optics in whispering-gallery-mode (WGM) microresonators have attracted much attention. Owing to strong confinement of the light in a small volume, a WGM microresonator ca…
Suppression of bend loss in writing of three-dimensional optical waveguides with femtosecond laser pulses
Zhengming Liu, Yang Liao, Zhiwei Fang +2
We provide a solution toward compact and low-loss three dimensional (3D) photonic circuits by femtosecond laser direct writing of 3D waveguides in fused silica. We suppress the ben…
