Abstract

It is demonstrated experimentally that amplitudes of defect modes of one-dimensional photonic crystal have maximal value near edges of the photonic band gap while at the centre of the stop-band they are reduced, moreover than more number of layers in photonic crystal, the less the amplitude of defect mode at the center of the PBG. We explain such behavior of defect modes presence of losses at propagation of light in real photonic crystal structures.
