NFYK12010U  Quantum Nanophotonics

Volume 2014/2015

Quantum optics in solid-state nanophotonics systems is a rapidly progressing research field that focuses on controlling the interaction between light and matter.

The course will provide an introduction to the quantum optical description of light-matter interaction in nanophotonic structures. The physics of dielectric nanophotonics structures will be discussed in details including photonic crystal cavities and waveguides. Furthermore, the optical properties of solid-state light emitters (quantum dots) are introduced. The interaction between photons and quantum dots provides the core of the course including the discussion of Wigner-Weisskopf theory of spontaneous emission in nanostructures, the master equation description of light-matter interaction with dephasing, and cavity quantum electrodynamics. In the later part of the course examples of modern research topics will be discussed including also experimental aspects of highly-efficient single-photon sources and basic quantum information

Learning Outcome

The aim of the course is to bring the students at a level where they are capable of comprehending modern research literature on quantum nanophotonics.

Specifically, after following this course students should be able to:


  • discuss the concept of dephasing and the consequences for light emission
  • analyze the different quantum electrodynamics regimes for a quantum emitter in a cavity
  • discuss methods of creating an efficient single-photon source and the applications of it
  • discuss basic quantum information protocols implemented in solid-state systems


  • describe basic principles of photonic crystals
  • explain the concepts of photonic crystal cavities and waveguides
  • explain fundamental principles of light emission from quantum dots
  • account for the theory of spontaneous emission in photonic nanostructures

This course will provide the students with a competent background for doing research within solid-state quantum optics, i.e. through a M.Sc. project.

It is requested that the students have followed the Quantum Optics course or something similar. It is assumed that the students have a good background in quantum mechanics, e.g., through following the physics curriculum of the first three years or something similar.
