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…
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…
Asymmetrical estimator for training encapsulated deep photonic neural networks
Yizhi Wang, Minjia Chen, Chunhui Yao +4
Photonic neural networks (PNNs) are fast in-propagation and high bandwidth paradigms that aim to popularize reproducible NN acceleration with higher efficiency and lower cost. Howe…
Dilated space-and-wavelength selective crosspoint optical switch
Ziyao Zhang, Minjia Chen, Rui Ma +4
Photonic integrated switches that are both space and wavelength selective are a highly promising technology for data-intensive applications as they benefit from multi-dimensional m…
Ultra-low-crosstalk Silicon Switches Driven Thermally and Electrically
Peng Bao, Chunhui Yao, Chenxi Tan +5
Silicon photonic switches are widely considered as a cost-effective solution for addressing the ever-growing data traffic in datacenter networks, as they offer unique advantages su…
