Electromagnetic Wavesce the wave equation for the electric field in vacuum. For its most frequently used solution to describe light - the plane harmonic wave - we formulate the essential properties of light waves, the relations between the oscillating electromagnetic fields, and the propagation parameters. Then we inclu

Photonsimportance of dispersion relations for the understanding of particle properties. It should be noted, that we will discuss here the quantum aspects of light on an elementary level only. We will come back to a comprehensive review of photon physics and the area of quantum optics in the second volume o

Density of States and Distribution Functionsch can then also be used throughout this book for the statistics of any type of (quasi-)particles including systems of reduced dimensionality. To describe the probability that the available states are occupied with (quasi-)particles we will introduce respective . for fermionic and bosonic particles.

Macroscopic Optical Properties of Solidsa homogeneous medium described by the complex dielectric function . or by the complex index of refraction .. We concentrate especially on the reflection and transmission of light at the plane interface between two media. As an especially simple case we investigate the boundary of matter and vacuum.

Microscopic Aspects of Weak Light-Matter Coupling between light and matter from a microscopic point of view. We use here the perturbative or weak-coupling approach for this interaction, which is in most cases sufficient for dilute systems such as gases. For solids the strong-coupling approach is often necessary. This leads to the concept of polari

The Crystal Lattice and Reciprocal Spaceticular we lay out the basis for the following chapters where we consider elementary excitations and so-called quasi-particles in semiconductors. These will be needed to describe and understand the linear optical properties. The properties of the quasi-particles themselves are governed by the underl

Vibrations of Atoms in a Crystal Lattice many textbooks (e.g., Ashcroft et al. in Solid State Physics. Cengage Learning Asia, Singapore, 2016 [.]). We will start with a homogeneous string, proceed to mono-atomic and diatomic chains and finally arrive at the three-dimensional arrangement found in solids. The resulting quanta of these latti
