Inverse Design in Photonics

“Inverse design” is a technique for automated photonic device design. The process involves mathematically defining a “figure of merit” for one’s device and then using gradient-based optimization to efficiently maximize this function with respect to a large number of design parameters. In this section, we introduce the basics of inverse design, discuss its connections to other techniques in deep learning, and give practical examples of how it is used to design photonic devices in Tidy3D.
