Abstract
Using a rigorous differential theory of diffraction gratings, we have investigated the optical properties of some peculiar bandgap structures. We have dealt wit devices made of two stacks of equidistant rod gratings separated by a central planar defect which leads to the occurrence of a transmission peal inside the wavelength bandgap. We have studied how the stability of the effective bandgaps copes with fluctuations of various experimental parameters. For various bandgaps and polarizations in structures including a defect we have studied the resulting filter characteristics and its possibilities as optical switch when the defect is made of nonlinear materials. As long as plastics have convenient refractive indices, optical losses and nonlinearities, the devices we describe could be manufactured using such materials.
