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…
Engineering Phonon Polaritons in van der Waals Heterostructures to Enhance In-Plane Optical Anisotropy
Kundan Chaudhary, Michele Tamagnone, Mehdi Rezaee +4
Van der Waals heterostructures assembled from layers of 2D materials have attracted considerable interest due to their novel optical and electrical properties. Here we report a sca…
Selective excitation and imaging of ultraslow phonon polaritons in thin hexagonal boron nitride crystals
Antonio Ambrosio, Michele Tamagnone, Kundan Chaudhary +4
Polaritons in 2D and van der Waals (vdW) materials have been investigated in several recent works as an innovative platform for light-matter interaction, rich of new physical pheno…
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…
