High-efficiency edge couplers enabled by vertically tapering on lithium-niobate photonic chips
Di Jia, Qiang Luo, Chen Yang +7
In the past decade, photonic integrated circuits (PICs) based on thin-film lithium niobate (TFLN) have advanced in various fields, including optical communication, nonlinear photon…
Local perfect chirality at reflection-zeros away from exceptional points in optical whispering gallery microcavity
Junda Zhu, Haitao Liu, Fang Bo +3
Recently, a local and imperfect chirality of the resonant eigenmode at the exceptional point (EP) has been reported in the optical whispering gallery microcavity system perturbed b…
Photonic chip-based high-efficiency soliton microcombs via electroopitc-Kerr synergy
Rui Niu, Shuai Wan, Pi-Yu Wang +8
Temporal soliton mode-locking in coherently pumped microcavities provides a promising platform for miniaturized frequency comb systems. While significant progress has been made, ac…
On-chip erbium-doped lithium niobate waveguide amplifiers
Qiang Luo, Chen Yang, Zhenzhong Hao +6
Lithium niobate on insulator (LNOI), as an emerging and promising optical integration platform, faces shortages of on-chip active devices including lasers and amplifiers. Here, we…
Broadband highly efficient nonlinear optical processes in on-chip integrated lithium niobate microdisk resonators of Q-factor above 10^8
Renhong Gao, Haisu Zhang, Fang Bo +9
We demonstrated broadband highly efficient optical nonlinear processes in on-chip integrated lithium niobate (LN) microdisk resonators. The Q factors of the micro-resonators fabric…
Dirac-vortex topological cavity
Xiaomei Gao, Lechen Yang, Hao Lin +5
Cavity design is crucial for single-mode semiconductor lasers such as the distributed feedback (DFB) and vertical-cavity surface-emitting lasers (VCSEL). By recognizing that both o…
