Efficiency of Launching Highly Confined Polaritons by Infrared Light Incident on a Hyperbolic Material

Efficiency of Launching Highly Confined Polaritons by Infrared Light Incident on a Hyperbolic Material

We investigated phonon-polaritons in hexagonal boron nitride - a naturally hyperbolic van der Waals material - by means of the scattering-type scanning near-field optical microscopy. Real-space nanoimages we have obtained detail how the polaritons are launched when the light incident on a thin hexag...
