Polariton Nanophotonics using Phase Change Materials

Kundan Chaudhary, Michele Tamagnone, Xinghui Yin +14

Polaritons formed by the coupling of light and material excitations such as plasmons, phonons, or excitons enable light-matter interactions at the nanoscale beyond what is currentl…

High quality factor polariton resonators using van der Waals materials

Michele Tamagnone, Kundan Chaudhary, Christina M. Spaegele +6

We present high quality factor optical nanoresonators operating in the mid-IR to far-IR based on phonon polaritons in van der Waals materials. The nanoresonators are disks patterne…

Guided Modes of Anisotropic van der Waals Materials Investigated by Near-Field Scanning Optical Microscopy

Daniel Wintz, Kundan Chaudhary, Ke Wang +11

Guided modes in anisotropic two-dimensional van der Waals materials are experimentally investigated and their refractive indices in visible wavelengths are extracted. Our method in…
