## Inverse design of grating coupler

Inversely design a silicon-on-insulator grating coupler using the built-in parametrized geometry optimization module (PO) for FDTD. Compared to other optimization methods such as particle swarm optimization (PSO), this optimization algorithm enables obtaining the best solution in just a few iterations. In this example, the etch depth will be fixed at Więcej…
