Surface plasmon influenced Pancharatnam-Berry geometric phase in Young's arrangement

Aleksi Leinonen, Ari T. Friberg, Tommi K. Hakala

Institute of Photonics, University of Eastern Finland, Finland

We theoretically study how surface plasmons influence the Pancharatnam--Berry geometric phase of light in a metallic Young's two-slit arrangement by using a phenomenological model. The surface plasmon is found to influence the magnitude of the Pancharatnam--Berry geometric phase if the symmetry of the system is broken at geometry or polarization level. Additionally, nonidentical apertures and different surface plasmon propagation distances can have a major impact on the induced Pancharatnam--Berry phase.

T-matrix based scattering analysis of photonic materials with periodicity in different dimensions

Dominik Beutel, Carsten Rockstuhl, Ivan Fernandez-Corbaton

Karlsruhe Institute of Technology, Germany

Optical devices and artificial photonic materials frequently make use of periodic arrangements of identical scatterers in 3D, 2D, and 1D, e.g. photonic crystals, meta-surfaces, or particle chains. To simplify their analysis, we present here a computational framework based on the T-matrix method that explicitly exploits spherical, cylindrical, and plane waves depending on the geometry and number of dimensions of the lattice. Due to the analytic properties of the chosen basis sets in combination with the use of Ewald's method for the lattice summation, we obtain an efficient framework to simulate such systems. The applicability will be illustrated at the conference by means of selected examples of contemporary interest.

Switchable optics based on guided mode resonance in lithographically patterned vanadium dioxide

Markus Walther, Thomas Siefke, Kristin Gerold, Uwe D. Zeitner

Friedrich Schiller University Jena, Institute of Applied Physics, 07745 Jena, Germany

Vanadium dioxide as a phase change material is usually known for its consideration in smart window applications. However, the attention shifts to using it in actively switched optical elements. The main challenges are the deposition of vanadium dioxide with the correct stoichiometry and phase and the patterning of the material. We propose a design with a corresponding manufacturing process for an actively switchable reflector at 1550 nm wavelength with a contrast near 10^5 by using the thermochromic effect of vanadium dioxide. The reflectance of the proposed optical element can be controlled between an ultra-low and a high reflecting state. We elaborate on the proposed optical design, the manufacturing process including deposition, annealing and patterning processes, and discuss already achieved results.

Tailoring magnetic dipole emission by broken-symmetry TiO2 metasurfaces

Ayesheh Bashiri, Aleksandr Vaskin, Katsuya Tanaka, Thomas Pertsch, Isabelle Staude

Friedrich Schiller University Jena, Germany

Strong magnetic dipole emission is offered by rare earth ions such as trivalent lanthanides, due to selection rule forbidden electric dipole (ED) transitions. This stimulates the study of optical nanostructures, which efficiently tailor magnetic dipole emission. High refractive index all dielectric nanostructures are promising candidates in this regard due to their strong magnetic response and negligible absorption loss in the visible spectral range. Here, we design and experimentally realize a broken-symmetry titanium dioxide (TiO2) metasurface supporting an out-of-plane magnetic dipole (MD) resonance at 590 nm wavelength, corresponding to the MD transition of trivalent Europium ions (Eu3+). A strong photoluminescence (PL) enhancement of the MD transition up to a factor of 15.5 is observed.
