nanowires as local sources for surface plasmon polaritons (SPPs). Photoexcited
semiconductor nanowires decay non-radiatively exciting SPPs when
they are on top of a metallic surface. We have investigated the anisotropic
excitation of SPPs by nanowires by placing individual InP nanowires inside
gold bullseye gratings. The gratings serve to couple SPPs to free space
radiation that is detected with a scanning confocal microscope. The circular
geometry of the grating allows to conclude that SPPs are preferentially
generated in the direction along the nanowire axis.

Abstract

We demonstrate a novel functionality of semiconductor
nanowires as local sources for surface plasmon polaritons (SPPs). Photoexcited
semiconductor nanowires decay non-radiatively exciting SPPs when
they are on top of a metallic surface. We have investigated the anisotropic
excitation of SPPs by nanowires by placing individual InP nanowires inside
gold bullseye gratings. The gratings serve to couple SPPs to free space
radiation that is detected with a scanning confocal microscope. The circular
geometry of the grating allows to conclude that SPPs are preferentially
generated in the direction along the nanowire axis.
