ABSTRACT
We use evolutionary algorithms to design photonic crystal structures with large band gaps. Starting from randomly generated photonic crystals, the algorithm yielded a photonic crystal with a band gap (defined as the gap to midgap ratio) as large as 0.3189. This band gap is an improvement of 12.5% over the best human design using the same index contrast platform.
