Abstract

Inspired by the multilayer structure of the cuticle of some gold beetles whose shell exhibits broadband reflection in the visible wavelength range, we numerically analyzed irregularly chirped dielectric mutilayers. The analysis was performed using a dedicated genetic algorithm which searches for the multilayer configurations that maximizes the reflection bandwidth. We found that the genetic algorithm leads to irregularly chirped structures which significantly outperform the regularly chirped ones proposed and analyzed in literature.
