Abstract
In some embodiments, a method for designing a photonic device is provided. A design optimization system receives an initial design for the photonic device. The initial design includes one or more inputs, one or more outputs, a number of subcomponent regions, and a number of waveguides for connecting the subcomponent regions. The design optimization system simulates each subcomponent region to determine simulated s-parameters of each subcomponent region. The design optimization system determines overall s-parameters for a simulated photonic device based on the simulated s-parameters of each subcomponent region and s-parameters of the waveguides. The design optimization system determines an overall gradient associated with the overall s-parameters. The design optimization system optimizes one or more subcomponent regions based on the overall gradient to create an updated design for the photonic device.
