3D-printed facet-attached optical elements for beam shaping in optical phased arrays
Stefan Singer, Yilin Xu, Sebastian Tobias Skacel +10
We demonstrate an optical phased-array (OPA) equipped with a 3D-printed facet-attached element for shaping and deflection of the emitted beam. The beam shaper combines freeform ref…
Efficient treatment of stacked metasurfaces for optimizing and enhancing the range of accessible optical functionalities
Christoph Menzel, Jan Sperrhake, Thomas Pertsch
We present, discuss and validate an adapted S-matrix formalism for an efficient, simplified treatment of stacked homogeneous periodically structured metasurfaces operated under nor…
Characterization of a circular optical nanoantenna by nonlinear photoemission electron microscopy
Thomas Kaiser, Matthias Falkner, Jing Qi +5
We report on the investigation of an advanced circular plasmonic nanoantenna under ultrafast excitation using nonlinear photoemission electron microscopy (PEEM) under near-normal i…
Homogenization of resonant chiral metamaterials
Andrei Andryieuski, Christoph Menzel, Carsten Rockstuhl +3
Homogenization of metamaterials is a crucial issue as it allows to describe their optical response in terms of effective wave parameters as e.g. propagation constants. In this pape…
An advanced Jones calculus for the classification of periodic metamaterials
Christoph Menzel, Carsten Rockstuhl, Falk Lederer
By relying on an advanced Jones calculus we analyze the polarization properties of light upon propagation through metamaterial slabs in a comprehensive manner. Based on symmetry co…
Asymmetric transmission of linearly polarized light at optical metamaterials
C. Menzel, C. Helgert, C. Rockstuhl +4
We experimentally demonstrate a three-dimensional chiral optical metamaterial that exhibits an asymmetric transmission for forwardly and backwardly propagating linearly polarized l…
