Fundamentals of Semiconductor Optoelectronics and Photonics

The emphasis of this two-day course is on providing basic background material for understanding semiconductor optoelectronics as well as a clear understanding of the fundamental operating principles and state-of-the-art of diode lasers, LEDs, modulators and detectors. The course will also describe how devices are designed, produced, evaluated, handled and operated, and will present a comprehensive overview of currently available optoelectronic and photonic devices and discuss current areas of development. The course notes have been updated to ensure timeliness and relevance. This course will be of value to those working in the field of optics and to those using optoelectronic devices in all applications.

We offer this and all courses as On Site Training
