Yu Dian Lim, Yun Da Chua, Wai Cheung Ma, Yeow Kheng Lim, Chuan Seng Tan
A mixed-pitch grating coupler which can couple a wide range of wavelengths is preferred in its application in co-packaged optics (CPO). However, the design and optimization of such grating coupler is complex. In this work, we developed software with integrated deep neural network…
