Abstract
We use stochastic adjoint optimization to design a new class of integrated photonics devices. They can accomplish highly sophisticated task of information processing such as image recognition. It combines stochastic gradient decent and adjoint state method to solve the optimization problem in nonlinear Maxwell's equations. We also develop approaches to control the minimal feature sizes of the designed devices for easy fabrication.
