Plasmonic Antenna Coupling to Hyperbolic Phonon-Polaritons for Sensitive and fast Mid-Infrared Photodetection with Graphene
(Nature, 2020-09-25)
Integrating and manipulating the nano-optoelectronic properties of Van der Waals heterostructures can enable unprecedented platforms for photodetection and sensing. The main challenge of infrared photodetectors is to funnel ...
Focusing of in-plane hyperbolic polaritons in van der Waals crystals with tailored infrared nanoantennas
(American Association for the Advancement of Science, 2021-10)
[EN]Phonon polaritons (PhPs)-light coupled to lattice vibrations-with in-plane hyperbolic dispersion exhibit ray-like propagation with large wave vectors and enhanced density of optical states along certain directions on ...
Microcavity phonon polaritons from the weak to the ultrastrong phonon–photon coupling regime
(Nature Research, 2021-10-27)
[EN]Strong coupling between light and matter can be engineered to influence their properties and behaviour. Here, the authors demonstrate the evolution from weak to ultrastrong coupling of microcavity modes and optical ...
Planar refraction and lensing of highly confined polaritons in anisotropic media
(Nature, 2021-07-15)
Refraction between isotropic media is characterized by light bending towards the normal to the boundary when passing from a low- to a high-refractive-index medium. However, refraction between anisotropic media is a more ...
