Laser beam propagation in optically active one-dimensional photonic crystals

Abstract

The problem of Gaussian beam reflection from and propagation through the finite sequence of anisotropic chiral slabs is studied. Effects of the permittivity and permeability frequency dispersion on the beam propagation and scattering are analyzed with a special emphasis on the regimes with negative real parts of /spl epsiv//spl I.cap/(/spl omega/) and /spl mu//spl I.cap/(/spl omega/).
