Recent developments in computational freeform inverse design have provided a fertile landscape of structures and topologies for nanophotonics, especially for the design of integrated optical devices such as waveguides and mode converters. However, simply dumping millions of parameters into a simulation can easily lead to intractable computational problems. Fortunately, a given engineering problem often admits many different mathematical formulations, and by carefully matching the formulation to the available electromagnetic solvers and optimization algorithms one can set the stage for extraordinarily flexible automated design. In this talk, I will discuss a variety of carefully formulated inverse design problems, ranging from light confinement in multi-resonant nonlinear cavities, designing exotic spectral features in photonic crystals to beam-forming and manipulation through multi-layered metasurfaces.
