Deep learning for inverse design of photonic devices
Abstract/Contents
- Abstract
- Inverse design of photonic devices is to use optimization algorithms to discover optical structures for desired functional characteristics. However, most of these inverse design problems are non-convex in a very high-dimensional space. This thesis will discuss the use of deep learning as an efficient tool for the inverse design of photonic devices. First, I apply Generative Adversarial Networks (GANs) to 3D metagrating design to augment high-performing device patterns. Next, I introduce Global Optimization Networks (GLOnets) which replace the discriminator in GANs with an electromagnetic solver and then train the generator directly from the solver by backpropagating gradients calculated by the adjoint variable method. Then we apply GLOnets to optical multi-layer thin-film stack design. Next, we analyze the mathematical principles behind GLOnets and explain their advantages. Finally, I discuss the application of neural networks as surrogate simulators to speed up simulations in the inverse design. Overall, we envision that combing the modeling capability of deep neural networks and existing physics knowledge could transform the way photonic systems are simulated and designed.
