Abstract

The dispersion relations of multilayer dye-doped hyperbolic metamaterials (HMM) are studied. We show that metallic losses can be greatly compensated by saturated gain. Two realizable applications using gain-assisted HMMs, namely hypergratings and epsilon-near-zero materials, are proposed.
