Abstract
Dielectric structures, in particular periodic dielectric structures are treated. A general one-dimensional model is developed describing Bragg mirrors. Examples for photonic band gap materials in one, two and three dimensions are given. Different types of dielectric cavities and microscopic resonators including Fabry–Pérot and whispering gallery resonators are treated. Quantum electrodynamic physical effects from light matter coupling such as Purcell effect and strong coupling are treated.

Notes
- 1.
This is a general property of Maxwell’s equations which do not contain a specific length scale.
- 2.
These solutions only occur for sufficient oscillator strength \(f>(\varGamma /\omega _0)^2\), i.e. in the strong coupling regime where \(\varOmega _0^2>0\). The absorption coefficient at \(\omega _0\) must be larger than \(\varGamma n_{\infty }/c\).
- 3.
V is given by the spatial integral of the vacuum field intensity for the cavity mode, divided by its maximum value.
- 4.
We note that besides the green luminescence as in Fig. 10.20, an unstructured green band also occurs that is observed here. Its origin may be linked to the oxygen vacancy [1383].
