On-chip arrayed waveguide grating fabricated on thin film lithium niobate
Zhe Wang, Zhiwei Fang, Zhaoxiang Liu +8
We design an on-chip 8-channel TFLN AWG and fabricate the device using photolithography assisted chemo-mechanical etching (PLACE) technique. We experimentally measure the transmiss…
Multi-mode Perturbation Modelling for Cavity Polygon and Star Modes
Saeed Farajollahi, Zhiwei Fang, Jintian Lin +3
Polygon and star modes enable unidirectional emission and single-frequency lasing in whispering gallery microcavities. To understand their properties and facilitate design, we have…
Electro-optically programmable photonic circuits enabled by wafer-scale integration on thin-film lithium niobate
Yong Zheng, Haozong Zhong, Haisu Zhang +10
Programmable photonic circuits performing universal linear-optical transformations underpin vital functions in photonic quantum information processing, quantum-enhanced sensor netw…
JDRec: Practical Actor-Critic Framework for Online Combinatorial Recommender System
Xin Zhao, Zhiwei Fang, Yuchen Guo +3
A combinatorial recommender (CR) system feeds a list of items to a user at a time in the result page, in which the user behavior is affected by both contextual information and item…
Monolithic integration of a high-quality factor lithium niobate microresonator with a free-standing membrane waveguide using femtosecond laser assisted ion beam writing (FLAIBW)
Zhiwei Fang, Yingxin Xu, Min Wang +4
We demonstrate integrating a high quality factor lithium niobate microdisk resonator with a free-standing membrane waveguide. Our technique is based on femtosecond laser direct wri…
On-chip electro-optic tuning of a lithium niobate microresonator with integrated in-plane microelectrodes
Min Wang, Yingxin Xu, Zhiwei Fang +7
We demonstrate electro-optic tuning of an on-chip lithium niobate microresonator with integrated in-plane microelectrodes. First two metallic microelectrodes on the substrate were…
