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…
Mechanical detection and imaging of hyperbolic phonon polaritons in hexagonal Boron Nitride
Antonio Ambrosio, Luis A. Jauregui, Siyan Dai +7
Mid-infrared nano-imaging and spectroscopy of two-dimensional (2D) materials have been limited so far to scattering-type Scanning Near-field Optical Microscopy (s-NSOM) experiments…
Using the Discrete Dipole Approximation and Holographic Microscopy to Measure Rotational Dynamics of Non-spherical Colloidal Particles
Anna Wang, Thomas G. Dimiduk, Jerome Fung +4
We present a new, high-speed technique to track the three-dimensional translation and rotation of non-spherical colloidal particles. We capture digital holograms of micrometer-scal…
