Layer-Resolved Absorption of Light in Arbitrarily Anisotropic Heterostructures
Nikolai Christian Passler, Mathieu Jeannin, Alexander Paarmann
We present a generalized formalism to describe the optical energy flow and spatially resolved absorption in arbitrarily anisotropic layered structures. The algorithm is capable of…
Surface Polariton-Like s-Polarized Waveguide Modes in Switchable Dielectric Thin-Films on Polar Crystals
Nikolai Christian Passler, Andreas Heßler, Matthias Wuttig +2
Surface phonon polaritons (SPhP) and surface plasmon polaritons (SPP), evanescent modes supported by media with negative permittivity, are a fundamental building block of nanophoto…
Surface phonon polariton resonance imaging using long-wave infrared-visible sum-frequency generation microscopy
Riko Kiessling, Yujin Tong, Alexander J. Giles +5
We experimentally demonstrate long-wave infrared-visible sum-frequency generation microscopy for imaging polaritonic resonances of infrared (IR) nanophotonic structures. This nonli…
Low-temperature infrared dielectric function of hyperbolic -quartz
Christopher J. Winta, Martin Wolf, Alexander Paarmann
We report the infrared dielectric properties of -quartz in the temperature range from to . Using an infrared free-electron laser, far-infrared…
Controlling Nanoscale Air-Gaps for Critically Coupled Surface Polaritons by Means of Non-Invasive White-Light Interferometry
Karsten Pufahl, Nikolai Christian Passler, Nicolai B. Grosse +3
We report an experimental method to control large-area air-gaps in the nanometer range for evanescent coupling of light to surface waves such as surface plasmon polaritons or surfa…
Strong Coupling of Epsilon-Near-Zero Phonon Polaritons in Polar Dielectric Heterostructures
Nikolai Christian Passler, Christopher R. Gubbin, Thomas Graeme Folland +7
We report the first observation of epsilon near zero (ENZ) phonon polaritons in an ultrathin AlN film fully hybridized with surface phonon polaritons (SPhP) supported by the adjace…
