Abstract

The optimization of the quality factor (Q) of photonic resonators is of great importance for applications exploiting both ordered and disordered systems. Here we propose a gradient-based automated optimization approach to maximize the Q of optical resonances in ordered and disordered dielectric slabs which uses first-order non-hermitian perturbation theory. By applying our method to optimize a selected Anderson mode in a random design exhibiting a Q-factor of 200, a new mode displaying Q = 10⁵ is generated.
