Directional light emission from nanowire structures

Abstract

A central topic of nanophotonics is to control the light emission by exploiting the interaction between different emission sources and nanostructures. As typical one-dimensional nanostructures, nanowires have proved to be a promising candidate to shape the property of light emission, either from itself or from other dedicated sources in its vicinity. In this thesis we will investigate the emission directivity of two different nanowire structures, namely vertical nanowire dimers and horizontal single nanowires. We will demonstrate that the emission directivity from a nanowire can be tailored by designing a multi-nanowire ensemble or by confining the source position inside the nanowire. We believe that the results of this thesis are meaningful for the purpose of designing nanowire-based light sources such as nanowire LEDs and single photon sources.
