Isotopic enrichment in hexagonal boron nitride is shown to enhance the propagation properties of phonon polaritons, achieving a threefold enhancement in their lifetime. Conventional optical components are limited to size scales much larger than the wavelength of light, as changes to the amplitude, p...
