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…
Laser radio transmitter
Marco Piccardo, Michele Tamagnone, Benedikt Schwarz +8
Since the days of Hertz, radio transmitters have evolved from rudimentary circuits emitting around 50 MHz to modern ubiquitous Wi-Fi devices operating at gigahertz radio bands. As…
Graphene Reflectarray Metasurface for Terahertz Beam Steering and Phase Modulation
Michele Tamagnone, Santiago Capdevila, Antonio Lombardo +6
We report a THz reflectarray metasurface which uses graphene as active element to achieve beam steering, shaping and broadband phase modulation. This is based on the creation of a…
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…
