Abstract

The field of nanophotonics is based on the ability to confine light to sub-diffractional dimensions. In the infrared, this requires compression of the wavelength to length scales well below that of the free-space values, which requires the implementation of polaritons, such as the plasmon and phonon polaritons. Here we will discuss the opportunity to implement polaritonic strong coupling between different media in an effort to dictate the polaritonic dispersion relation, and thus, the propagation and resonant properties of these materials. Within the talk results highlighting ultra-strong coupling in both forms of polaritons will be presented in the context of infrared emitters, as a means to control planar propagation using hyperbolic polaritons and in an effort to dictate the IR dielectric function using superlattice designs, with n-doped CdO offering an exemplary material in this regard.
