Abstract
Nano-Optics studies the interaction of light and matter at the sub-wavelength scale. It is a flourishing field of fundamental and applied research and it is enabled by the rapid advance of nanotechnology. Nano-optics embraces topics such as optical antennas, meta-materials, novel opto-electronic materials, optical trapping and manipulation, and super-resolution imaging and spectroscopy.
Objective
The goal of this course is to understand the fundamental concepts governing light-matter interactions on the sub-wavelength scale. A further objective is to gain an overview over the recent developments in the fields of optical imaging, optical manipulation, and low-dimensional optical materials.
Content
We start with the angular spectrum representation of fields to understand the classical resolution limit. We continue with the theory of strongly focused light, the point spread function, and resolution criteria of conventional microscopy, before turning to super-resolution techniques, based on near- and far-fields. We introduce the local density of states and approaches to control spontaneous emission rates in inhomogeneous environments, including optical antennas. Then, we touch upon optical forces and their applications in optical tweezers. Finally, we discuss recent advances regarding optoelectronics with 2D materials
