Optical properties of disordered metallic photonic crystal slabs

Abstract

We give an overview about the optical properties of disordered metallic photonic crystal slabs. Different disorder models with different next-neighbor correlations are artificially introduced into the samples, and their influence on the samples' transmission and bandstructure are examined. We found that uncorrelated disorder reduces the amplitude of spectral features and the width of the stop-bands in the bandstructure. Correlated disorder additionally excites multiple resonances, resulting in broadened resonances and a destroyed bandstructure even at moderate disorder. Numerical results are presented that allow to fully interpret the experimental observations. © 2007 WILEY-VCH Verlag GmbH & Co. KGaA.
