More Information
Summary:In some embodiments, a computer-implemented method for designing a physical device is provided. A computing system generates an initial design that includes an input waveguide starting at an input location and extending to a end position, an output waveguide starting at a start position and extending to an output location, and a dispersive region. The computing system determines a set of structural parameters based on the initial design. The computing system simulates performance of the initial design using the set of structural parameters to determine a performance loss value based on at least one performance goal. The computing system updates at least one of the end position of the input waveguide, the start position of the output waveguide, or a size of the dispersive region in the initial design using a gradient of the performance loss value.
