Experimental verification of the method for producing a three-dimensional cross-pairs metamaterial structure based on a dielectric AlN cube

Przemyslaw Andrzej Gorski

This paper presents a method of manufacturing 3D metamaterial structures using laser radiation. Our proposed material, aluminum nitride (AlN), by interaction of a high-energy laser beam undergoes a direct metallization process, a result of which a conducti ...

Acoustic dispersive prism

Juan Ramon Mosig, Hervé Lissek, Sami Driss Karkar, Seyyed Hussein Seyyed Esfahlani

The optical dispersive prism is a well-studied element, which allows separating white light into its constituent spectral colors, and stands in nature as water droplets. In analogy to this definition, the acoustic dispersive prism should be an acoustic dev ...

Transition of optical regime in miniaturized optical systems: light interactions beyond the refraction limit

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We investigate the transition of optical regimes of miniaturized optical systems using two canonical examples, where the refraction of light limits the system performance. A ball-lens and a solid immersion lens (SIL) are considered, whose refractive respon ...

Spectral signatures of high-symmetry quantum dots and effects of symmetry breaking

Elyahou Kapon, Alok Rudra, Marc-André Dupertuis, Daniel Oberli, Valentina Troncale

High symmetry epitaxial quantum dots (QDs) with three or more symmetry planes provide a very promising route for the generation of entangled photons for quantum information applications. The great challenge to fabricate nanoscopic high symmetry QDs is furt ...

Near Field Investigation of Bloch Surface Based Platform for 2D Integrated Optics

Hans Peter Herzig, Elsie Barakat, Richa Dubey

Dielectric multilayers sustaining Bloch surface waves (BSWs) are considered as a novel platform for two dimensional (2D) integrated optics. The dielectric platform is exploited to manipulate surface waves by patterning 2D dielectric optical components on t ...

Towards quantifying effects of refractive index mismatch on PIV results

Karen Ann J Mulleners, Sebastian Kurth

Refractive index matched particle image velocimetry (RIM-PIV) is an elegant method to measure velocity fields around complex geometries and in difficultly accessible areas. The accuracy of RIM-PIV is strongly affected by the quality of refractive index mat ...

Negative Refraction and Planar Focusing Based on Parity-Time Symmetric Metasurfaces

Romain Christophe Rémy Fleury

We introduce a new mechanism to realize negative refraction and planar focusing using a pair of parity-time symmetric metasurfaces. In contrast to existing solutions that achieve these effects with negative-index metamaterials or phase conjugating surfaces ...

(Re-)inventing the relativistic wheel: gravity, cosets, and spinning objects

Alexander Monin, Francesco Riva, Solomon G Shamsuddin Osman Endlich

Space-time symmetries are a crucial ingredient of any theoretical model in physics. Unlike internal symmetries, which may or may not be gauged and/or spontaneously broken, space-time symmetries do not admit any ambiguity: they are gauged by gravity, and an ...
