Sentences with phrase «phonon polaritons»

U.S. Naval Research Laboratory (NRL) scientists, in collaboration with researchers from the University of Manchester, U.K.; Imperial College, London; University of California San Diego; and the National Institute of Material Science (NIMS), Japan, have demonstrated that confined surface phonon polaritons within hexagonal boron nitride (hBN) exhibit unique metamaterial properties that enable novel nanoscale optical devices for use in optical communications, super-resolution imaging, and improved infrared cameras and detectors.

These surface phonon polaritons are analogous to electron oscillations in metals or doped - semiconductors, called plasmons, but offer the benefit of low losses and operation in the infrared to terahertz spectral regions.
