3D surface profiling via photonic integrated geometric sensor
Ziyao Zhang, Yizhi Wang, Chunhui Yao +11
Measurements of microscale surface patterns are essential for process and quality control in industries across semiconductors, micro-machining, and biomedicines. However, the devel…
Wavelength-agnostic 3D-Nanoprinted coupler
Huiyu Huang, Zhitian Shi, Chunhui Yao +2
We present a photonic coupler that exhibits effectively wavelength-agnostic performance for ultra-broadband optical interfacing. By incorporating a dual-ellipsoidal geometry, the d…
Tri-layer SiN-on-Si 8x8 Optical Switches with Thermo-optic and Electro-optic Actuators
Bohao Sun, Chunhui Yao, Tongyun Li +11
We present two spatial-multiplexed switch-and-select (S&S) 8x8 optical switches incorporating a tri-layer SiN-on-Si platform, one equipped with thermo-optic (T-O) and the other ele…
Optical Convolutional Spectrometer
Chunhui Yao, Jie Ma, Ningning Wang +12
Optical spectrometers are fundamental across numerous disciplines in science and technology. However, miniaturized versions, while essential for in situ measurements, are often res…
