Controlling dispersion and transmission spectra of hybrid resonant-gas-filled photonic-crystal optical components

Using the model of an infinite one-dimensional periodic layered structure, we consider the possibilities of controlling dispersion properties and tran smission spectra of hybrid optical components consisting of photonic band-g ap structures filled with a resonant gas. It is shown that the combination of resonance-enhanced gas dispersion with the dispersion of a photonic band -gap structure may give rise to new features in the dispersion and transmis sion of hybrid spectral elements. These effects can be employed to create n arrow-band filters and ultrarefractive prisms with controllable parameters. (C) 2000 MAIK "Nauka/Interperiodica".
