Nano-Optics

VVZ CR n/a

Last Updated: 2026-06-01 11:33:04

Abstract

Nano-Optics is the study of light-matter interaction at the sub-wavelength scale. It is a flourishing field of fundamental and applied research enabled by the rapid advance of nanotechnology. Nano-optics embraces topics such as structured light fields, optical antennas, optical trapping and manipulation, and high/super-resolution imaging and spectroscopy.

Objective

The goal is to understand the fundamental concepts governing light localization and light-matter interactions on the sub-wavelength scale.

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
