High-index-contrast single-mode optical waveguides fabricated on lithium niobate by photolithography assisted chemo-mechanical etching (PLACE)
Jianhao Zhang, Rongbo Wu, Min Wang +7
We report fabrication of low loss single mode waveguides on lithium niobate on insulator (LNOI) cladded by a layer of SiO2. Our technique, termed photolithography assisted chemo-me…
Fabrication of a multifunctional photonic integrated chip on lithium niobate on insulator using femtosecond laser assisted chemo-mechanical polish
Rongbo Wu, Jintian Lin, Min Wang +5
We report fabrication of a multifunctional photonic integrated chip on lithium niobate on insulate (LNOI), which is achieved by femtosecond laser assisted chemo-mechanical polish.…
High-precision measurement of a propagation loss of single-mode optical waveguides on lithium niobate on insulator
Jintian Lin, Junxia Zhou, Rongbo Wu +6
We demonstrate fabrication of single-mode optical waveguides on lithium niobate on insulator (LNOI) by optical patterning combined with chemo-mechanical polishing. The fabricated L…
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…
Lithium niobate micro-disk resonators of quality factors above 10^7
Rongbo Wu, Jianhao Zhang, Ni Yao +5
We report on fabrication of crystalline lithium niobate microresonators with quality factors above 10^7 as measured around 770 nm wavelength. Our technique relies on femtosecond la…
Fabrication of high quality factor lithium niobate double-disk using a femtosecond laser
Zhiwei Fang, Ni Yao, Min Wang +7
We demonstrate fabrication of a high quality factor lithium niobate double-disk whispering-gallery microcavity using femtosecond laser assisted ion beam milling. Using this method,…
