Efficiency and Uniformity Improvement of Micro-LED-Based Diffractive Waveguide Using Neural Network
In this paper, a cascaded multilayer perceptron was proposed to optimize the diffraction efficiency and uniformity of diffractive waveguide. Such a method is much faster than rigorous coupled wave analysis (RCWA) and ray tracing. After optimization, the exit pupil uniformity is increased from 0.36% to 97% a prediction accuracy exceeding 95% are realized. The proposed method is applicable to various types of gratings.
