A new multilayer optical film optimal method based on deep q-learning
This addresses a bottleneck for material researchers in optical applications like communication and filters, though it appears incremental as it applies an existing AI method to a new domain.
The authors tackled the problem of traditional numerical algorithms converging to local optima in multi-layer optical film design by introducing a deep Q-learning algorithm, which achieves global optimum convergence and greatly improves design efficiency.
Multi-layer optical film has been found to afford important applications in optical communication, optical absorbers, optical filters, etc. Different algorithms of multi-layer optical film design has been developed, as simplex method, colony algorithm, genetic algorithm. These algorithms rapidly promote the design and manufacture of multi-layer films. However, traditional numerical algorithms of converge to local optimum. This means that the algorithms can not give a global optimal solution to the material researchers. In recent years, due to the rapid development to far artificial intelligence, to optimize optical film structure using AI algorithm has become possible. In this paper, we will introduce a new optical film design algorithm based on the deep Q learning. This model can converge the global optimum of the optical thin film structure, this will greatly improve the design efficiency of multi-layer films.
