The combination of methods of micro‐ and macroscopic QED alows one to describe the influence of the absorbtion/ amplification and dispersion effects on the nonclassical radiation propagating through complex material systems. Within the framework of macroscopic QED the input‐otput formalism can be applied in order to include the arbitrary quantum state of the radiation field. On the other hand, the microscopic derivation of the emission spectra of a bulk semiconductor gives the physical interpretation of the noise current operators in the macroscopic theory. As an example, we investigate the propagation of the field being in squeezed vacuum state through a 5 μm ZnSe slab in absorbing and amplifying regimes. (© 2009 WILEY‐VCH Verlag GmbH & Co.
