Content of the lectures

The lectures consist of 4 SWh. (lectures and exercises). The lectures are suitable for students from 5 semester of "Nanostructure Science Course" (obligatory elective cource b/d, b/e, b/f) and "Physics Diploma" (elective cource S-Schein). Basic knowledge of Solid State Physics like "Introduction to the experimental physics IV" or "Applied semiconductor physics" are required.
The lectures present the fundamentals of laser physics based on semiconductor lasers and goes deeper into the current research of the laser device. The following topics will be discussed in the basic part of the lectures:

* spontaneous and stimulated emission
* spectral amplification
* threshold conditions
* Fabry-Perot resonator
* layers and core of the waveguide
* feedback and bragg grating
* theory of coupled modes
* transfer matrix theory
* high frequency properties (modulation properties, resonance frequency, chirp and line thickness)

The application area of the semiconductor lasers in the last 10 years was immensely broadened. It leads to mutiplicity of new applications and application possibilities, which will be discussed during the lectures and in the special topics of the seminar presentations. Among other things the nano-structuring methods for material and component structuring will be heightened in the future. Among other the following will be discussed:

* vertical emitting laser (VCSEL)
* disc and ring lasers
* microaser
* quantum dot laser
* UV-laser based on GaInN
* quantum cascade laser
* laser based on photonic crystals
* single photon source

In the lectures will be discussed also basic principles of the devices, fabrications methods and possible applications.
