Near-field investigation of Bloch surface wave based 2D optical components

Hans Peter Herzig, Myun Sik Kim, Elsie Barakat, Richa Dubey, Babak Vosoughi Lahijani

We study the Bloch surface wave based nano-thin 2D optical components. The 2D elements are fabricated on the dielectric multilayer platform which sustains the Bloch surface waves. Such a platform is considered as a novel foundation for planar integrated op ...

Subwavelength Focusing of Bloch Surface Waves

Hans Peter Herzig, Myun Sik Kim, Nicolas Maxime André Descharmes, Babak Vosoughi Lahijani

Microsized spheres can focus light into subwavelength spatial domains, a phenomenon called photonic nanojet. Even though well studied in three-dimensional (3D) configurations, only a few attempts have been reported to observe similar phenomena in two-dimen ...

Demonstration of Bloch Surface Waves in crystals with LiNbO3 thin films

Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal

A novel one dimensional photonic crystal (1DPHC) sustaining Bloch surface waves (BSWs) with a single crystal thin film lithium niobate (TFLN) as a part of a multilayer is theoretically and experimentally investigated. Properties of the dielectric multilaye ...

Advancing non-equilibrium ARPES experiments by a 9.3 eV coherent ultrafast photon source

Helmuth Berger, Philippe Bugnon, Alberto Crepaldi

The quest for investigating the non-equilibrium dynamics of the band structure of strongly-correlated materials over their entire Brillouin zone is a primary objective. However, the actual ultrafast UV light sources are not suitable for addressing several ...

Finite Element Modeling of Acoustic Shielding via Phononic Crystal structures

Clémentine Sophie Sarah Lipp, Andrea Lozzi

Quality factor of Contour Mode Resonators (CMR) are mainly affected by energy losses due to acoustic waves leaving the resonator through the anchors. An engineering of the anchors in order to create a periodic variation in the acoustic impedance of the mat ...

Surface States Transport in Topological Insulator Bi0.83Sb0.17 Nanowires

Jean-Philippe Ansermet

We investigate the transport properties of topological insulator (TI) nanowires. Single-crystal nanowire samples with diameters ranging from 75 nm to 1.1 m are prepared using high frequency liquid phase casting in a glass capillary; cylindrical single crys ...

Electromagnon dispersion probed by inelastic X-ray scattering in LiCrO2

Henrik Moodysson Rønnow, Christian Rüegg, Sándor Tóth

Inelastic X-ray scattering with meV energy resolution (IXS) is an ideal tool to measure collective excitations in solids and liquids. In non-resonant scattering condition, the cross-section is strongly dominated by lattice vibrations (phonons). However, it ...

Proposal for an Optomechanical Bell Test

Christophe Marcel Georges Galland

Photons of a laser beam driving the upper motional sideband of an optomechanical cavity can decay into photon-phonon pairs by means of an optomechanical parametric process. The phononic state can subsequently be mapped to a photonic state by exciting the l ...
