Angle-resolved cathodoluminescence nanoscopy

The field of microscopy is an important cornerstone of physical and biological sciences. The development of high-resolution microscopy/nanoscopy techniques has enabled a revolution in science and technology, greatly improving our understanding of the microscopic world around us, and forming the basis for the development of advanced nanotechnology. Similar to electrical integrated circuits there currently is a drive to miniaturize optical components with the aim to generate, detect, guide, or switch light on the nanoscale. To support this emerging field of nanophotonics, experimental techniques that can characterize optical properties on this length scale are required. In this thesis we present a novel experimental nanoscopy technique that can be used as a nanoscale characterization tool for optical properties: Angle-Resolved Cathodoluminescence (CL) Imaging Spectroscopy (ARCIS).
