Optoelectronics

Profile and objectives

This lab has two thematic clusters:  

-Optronics Lab

Students in this lab are taught in-depth knowledge of optical technologies and an overview of the variety of optical applications that can be found in many of the products developed by electronic engineers. The competences acquired include basic knowledge of the following fields:

  • Technical Optics (optics design: geometric optics and Gaussian optics)
  • Electronic and optical properties of laser diodes
  • Properties and applications of photodiodes
  • Interferometry and its applications (Michelson interferometer)
  • Polarization of light and its applications
  • Computer generated holograms
  • Properties and applications of optical fibers (optical time domain reflectometry, splicing, coupling of laser light into a single mode fiber)
  • Properties of grating spectrometers and application for the determination of Planck's quantum of action

-Advanced Physics Lab

The Advanced Physics Lab is attended by students of Electrical Power Engineering/Physics plus, who later either enter the engineering profession or become teachers at vocational schools (with physics as a second subject). Therefore, the goal of the lab is on the one hand to deepen and broaden future teachers’ understanding of physics, but on the other hand provide application-oriented knowledge of optical and physical technologies for future engineers. Students will acquire in-depth knowledge of optical technologies and conduct experiments on advanced topics in physics. The competences acquired include basic knowledge of the following fields:

  • Technical Optics (optics design: geometric optics and Gaussian optics)
  • Interferometry and its applications (Michelson interferometer)
  • Polarization of light and its applications
  • Computer generated holograms
  • Properties and applications of optical fibers (optical time domain reflectometry, splicing, coupling of laser light into a single mode fiber)
  • Determination of Planck's quantum of action with a vacuum photocell (counter field method) as an application of the external photo effect
  • Electron spin resonance
  • Hall effect

Equipment

The laboratory is a teaching and training laboratory and has, in addition to the set up experiments, a basic equipment of electrical and photometric measuring instruments. In addition, there is a pool of electronic, optical and optomechanical components and tools with which students can realize their own projects in the laboratory as part of project work and final theses.
