Extraordinary optical transmission and cathodoluminescence in thin layers with subwavelength holes — •Dan-Nha Huynh1, Christian Matyssek1, and Kurt Busch1,2 — 1Humboldt-Universität zu Berlin, Institut für Physik, AG Theoretische Optik und Photonik, Newtonstr. 15, 12489 Berlin, Germany — 2Max-Born-Institut, Max-Born-Str. 2A, 12489 Berlin, Germany
We examine properties of nano-plasmonic thin layers utilizing a self-implemented Discontinuous Galerkin Time-Domain (DGTD) program package. Specifically, metal films including subwavelength and wavelength-scale holes lead to interesting optical properties due to the excitation of surface plasmons such as extraordinary optical transmission.
We quantitatively explore the complex plasmon dynamics in these systems via optical transmission, electron energy loss and cathodoluminescence computations.
