Efficient pixel-by-pixel optimization of photonic devices utilizing the Dyson ’ s equation in a Green ’ s function formalism: Part I. Implementation with the method of discrete dipole approximation

Here, we introduce an efficient method to perform pixel-by-pixel optimization of photonic devices, based on the Dyson equation in the Green ’ s function formalism. Unlike continuous optimization techniques widely used for photonic device optimization, pixel-by-pixel optimization automatically ...
