Abstract

We show the possibility of polarization-selective amplification of a defect mode in an active photonic crystal through the excitation of surface plasmon resonance in a 2D periodic array of spheroidal metallic nanoparticles embedded in the structure. The array acts as a polarizer whose spectral characteristics depend on the shape of the nanoparticles and the periodicity of the array. The modal selectivity of the amplification is due to the strong dependence of the surface plasmon assisted light scattering by the nanoparticles on the relative orientations of their anisotropy axis and the polarization direction of the incoming light wave. We show that effective defect mode suppression, for a well-chosen polarization, can be achieved if the nanoparticles array is embedded in regions of high localization of the optical field.
