| Description | Over the past few years, hyperbolic metamaterials (HMMs) have attracted significant attention due to their extreme anisotropic permittivity and ease of fabrication using conventional thin film physical vapor deposition techniques, by depositing thin metal-dielectric multilayers in the effective medium regime. In particular, various material combinations have been used to engineer the dispersion relations of HMMs in different spectral bands. Notably, several applications of HMMs in a wide spectral band from visible to terahertz (THz) have been demonstrated by exploiting their extraordinary properties. However, the optical response of HMMs is usually fixed during fabrication. In this chapter, we discuss the tuning of optical responses of HMMs from visible to THz frequencies using different functional materials. Specifically, we discuss the design and development of active HMMs from visible to THz frequencies by incorporating suitable functional materials in multilayered HMMs. Moreover, we propose and discuss the potential applications of active HMMs in photonics and biomedical research.
