Abstract
In the infrared nanophotonics requires the compression of the wavelength of light to length scales below the diffraction limit. This can be achieved through the formation of polaritons, with two predominant forms being the plasmon and phonon polariton. Here we will discuss how leveraging polaritonic strong coupling and extreme forms of material anisotropy, such as the low symmetry of monoclinic or triclinic crystals can be used dictate the polaritonic dispersion relation, giving rise to novel optical phenomena such as hyperbolicity and shear polaritons. The talk will highlight ultra-strong polariton coupling in the context of IR emitters, to control light propagation and in modifying thermal dissipation at ultrafast time scales.
