    "abstract": "Recently a quantization scheme for the phenomenological Maxwell theory of the\nfull electromagnetic field in an inhomogeneous three-dimensional, dispersive,\nand absorbing dielectric medium has been developed and applied to a system\nconsisting of two infinite half-spaces with a common planar interface (H.T.\nDung, L. Knoell, and D.-G. Welsch, Phys. Rev. A 57, in press). Here we show\nthat the scheme, which is based on the classical Green-tensor integral\nrepresentation of the electromagnetic field, applies to any inhomogeneous\nmedium. For this purpose we prove that the fundamental equal-time commutation\nrelations of QED are preserved for an arbitrarily space-dependent,\nKramers--Kronig consistent permittivity. Further, an extension of the\nquantization scheme to linear media with bounded regions of amplification is\ngiven, and the problem of anisotropic media is briefly addressed.",
