Astrointerferometry with discrete optics
Stefano Minardi, Thomas Pertsch
We propose an innovative scheme exploiting discrete diffraction in a two dimensional array of coupled waveguides to determine the phase and amplitude of the mutual correlation func…
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…
Plasmonic modes of extreme subwavelength nanocavities
Joerg Petschulat, Christian Helgert, Michael Steinert +6
We study the physics of a new type of subwavelength nanocavities. They are based on U-shaped metal-insulator-metal waveguides supporting the excitation of surface plasmon polariton…
