DNN-assisted waveguide width extraction via optical measurement of a single low-order Mach-Zehnder interferometer

Abstract An accurate waveguide width extraction methodology is demonstrated by developing a deep-learning neural network (DNN) framework synergized with a single low-order Mach-Zehnder interferometer (MZI). Utilizing its intrinsic capacity for complex nonlinear capture, the proposed DNN achieves a s...
