Optoelectronics Course

Dr. Ted Dellin

This course is available as an 8 3/4 Hour narrated E learning course


     The importance of optoelectronics is growing rapidly.  Semiconductor optoelectronics is used to convert light into electricity (photodiode, solar cell) and to convert electricity into light (LED, laser diodes) .  This introductory, survey  course provides an easy-to-understand, intuitive approach to understanding semiconductor optoelectronics.    The only prerequisite is an introductory college physics course.

      The course consists of 17 modules as shown in the outline below.  The course includes the basic properties of semiconductors, how light is absorbed and emitted by semiconductors and the important devices (photodiode, solar cell, LED, laser diode).  Use the link above to see some sample slides.  Please note that the semiconductor and junction sections of this course are very similar to the corresponding sections of the VQS Microelectronics course.

      The  course is designed for engineers, scientists, technicians, managers, salesmen and investors.
