High-efficiency, cryogenic-compatible grating couplers on an AlN-on-sapphire platform through bottom-side coupling
Yiyu Zhou, Mohan Shen, Chunzhen Li +2
Sapphire is a commonly used substrate for wide-bandgap III-nitride photonic materials. However, its relatively high refractive index results in low transmission efficiency in grati…

Integrated photonic Galton board and its application for photon counting
Hezheng Qin, Risheng Cheng, Yiyu Zhou +1
The Galton board is a desktop probability machine traditionally used to visualize the principles of statistical physics with classical particles. Here, we demonstrate a photonic Ga…
