Broad Spectral Tuning of Ultra-Low Loss Polaritons in a van der Waals Crystal by Intercalation
Javier Taboada-Gutiérrez, Gonzalo Álvarez-Pérez, Jiahua Duan +17
Phonon polaritons (PhPs) -- light coupled to lattice vibrations -- in polar van der Waals (vdW) crystals are promising candidates for controlling the flow of energy at the nanoscal…
Negative reflection of polaritons at the nanoscale in a low-loss natural medium
Gonzalo Alvarez-Perez, Jiahua Duan, Javier Taboada-Gutierrez +10
Negative reflection occurs when light is reflected towards the same side of the normal to the boundary from which it is incident. This exotic optical phenomenon, which provides a n…
Active tuning of highly anisotropic phonon polaritons in van der Waals crystal slabs by gated graphene
Gonzalo Álvarez-Pérez, Arturo González-Morán, Nathaniel Capote-Robayna +5
Phonon polaritons (PhPs) -- lattice vibrations coupled to electromagnetic fields -- in highly anisotropic media display a plethora of intriguing optical phenomena (including ray-li…
Focusing of in-plane hyperbolic polaritons in van der Waals crystals with tailored infrared nanoantennas
Javier Martín-Sánchez, Jiahua Duan, Javier Taboada-Gutiérrez +9
Phonon polaritons (PhPs),light coupled to lattice vibrations,with in-plane hyperbolic dispersion exhibit ray-like propagation with large wavevectors and enhanced density of optical…
Twisted Nano-optics: Manipulating Light at the Nanoscale with Twisted Phonon Polaritonic Slabs
Jiahua Duan, Nathaniel Capote-Robayna, Javier Taboada-Gutierrez +5
Recent discoveries have shown that when two layers of van der Waals (vdW) materials are superimposed with a relative twist angle between their respective in-plane principal axes, t…
Infrared permittivity of the biaxial van der Waals semiconductor -MoO from near- and far-field correlative studies
Gonzalo Álvarez-Pérez, Thomas G. Folland, Ion Errea +13
The biaxial van der Waals semiconductor -phase molybdenum trioxide (-MoO) has recently received significant attention due to its ability to support highly anisotropic pho…
