Optoelectronics

What it is about

You learn the physical fundamentals and the design of modern semiconductor-based optoelectronics. The topic is electromagnetic waves and their interaction with materials, fundamental semiconductor physics as well as the structure and operating principles of LEDs, lasers (e.g. edge and VCSELs, DFB, quantum- and interband-cascade lasers) as well as photodetectors and solar cells. In the end you will be able to analyze the performance of such optoelectronic devices and assess simple designs.

What you will be able to do

• Understanding of Maxwell's equations, wave and Poynting theory
• Knowledge of optical layer systems, waveguides and resonators
• Fundamentals of semiconductor band structure, effective masses and density of states
• Distinction between spontaneous and stimulated emission
• Analysis and design of LEDs, semiconductor lasers and photodetectors
• Evaluation of different laser types (edge lasers, VCSEL, DFB, cascade lasers)
