Abstract

The electromagnetic transmission, reflection, and absorption characteristics of two-dimensional metallic photonic crystals with a coherent atomic gas as the host medium were systematically studied, with emphasis on the appearance and features of mini passbands within bandgaps of the unfilled (gas-free) crystals. Only normally incident s-polarized plane waves were considered. The mini passbands are connected with strong frequency dispersion of the relative permittivity of the host gas, being highly variable for a certain narrow regime of frequencies. Transmission effects similar to those connected with defect modes can appear in photonic crystals, which are associated with localization of dispersion in the frequency domain rather than with spatial localization of the field at structural defects. In addition, analogy with Fabry-Perot resonances is possible within the new bands. Their locations can be strongly sensitive to a variation of gas parameters so that they can be efficiently tuned at fixed frequency. Also, the occurrence of high-absorbance bands can be correlated with the frequency-dependent properties of the metal and the coherent atomic gas. Finally, the energy of the incident wave can be distributed in a desired proportion between either transmittance or reflectance on one hand and absorbance on the other.
