Integrated photonics on thin-film lithium niobate
Di Zhu, Linbo Shao, Mengjie Yu +12
Lithium niobate (LN), an outstanding and versatile material, has influenced our daily life for decades: from enabling high-speed optical communications that form the backbone of th…
Reconfigurable electro-optic frequency shifter
Yaowen Hu, Mengjie Yu, Di Zhu +7
Here we demonstrate an on-chip electro-optic frequency shifter that is precisely controlled using only a single-tone microwave signal. This is accomplished by engineering the densi…
Synthesis and Observation of Non-Abelian Gauge Fields in Real Space
Yi Yang, Chao Peng, Di Zhu +4
Gauge fields, real or synthetic, are crucial for understanding and manipulation of physical systems. The associated geometric phases can be measured, for example, from the Aharonov…
A General Theoretical and Experimental Framework for Nanoscale Electromagnetism
Yi Yang, Di Zhu, Wei Yan +7
Local, bulk response functions, e.g permittivity, and the macroscopic Maxwell equations completely specify the classical electromagnetic problem, which features only wavelength …
A Single-Photon Imager Based on Microwave Plasmonic Superconducting Nanowire
Qing-Yuan Zhao, Di Zhu, Niccolò Calandri +6
Detecting spatial and temporal information of individual photons by using single-photon-detector (SPD) arrays is critical to applications in spectroscopy, communication, biological…
