Visible range plasmons in topological insulators

Near-field imaging in the visible reveals the existence of localized and propagating plasmons on the surface of topological insulator. We also report ab-initio band structure calculations explain the origin of plasmonic response in chalcogenide compounds.

Ultra confined polaritons in atomically layered dielectrics

We report the first observation of highly confined polaritons with wavelength two orders of magnitude shorter than the free space wavelength that propagates on the surface of silicon carbide crystals covered by a few atomic layers of molybdenum disulfide.

Terahertz emission in one-dimensional disordered systems

Multimode terahertz (THz) laser emission around 3.2 THz in one-dimensional (1-D) disordered systems with 20% disorder. Simulation and experimental work provide evidence for spatial localization of light of defect modes within the bandgap frequency window.
