Abstract

Asymmetrical absorption plays an important role in applications such as photovoltaics, detectors, modulators and emitters. In this work, we introduce and numerically analyze a broadband device capable of realizing asymmetrical optical absorption depending on the direction of propagation of light. The proposed asymmetrical absorber is designed and optimized by a parametric search based on genetic algorithm.
