Semiconductor Optoelectronics

By Prof. M. R. Shenoy   |   IIT Delhi
Learners enrolled: 2386
This course introduces the students to the field of Semiconductor Optoelectronics, which deals with the physics and technology of semiconductor optoelectronic devices such as light emitting diodes, laser diodes and photodiodes, which are becoming important components in consumer optoelectronics, IT and communication devices, and in industrial instrumentation. Assuming a general science/engineering undergraduate level background, the course begins with a recap of essential (to this course) semiconductor physics, followed by the study of interaction of photons with electrons and holes in a semiconductor, leading to the realization of semiconductor photon amplifiers, sources, modulators, and detectors. A variety of designs and configurations of these devices have been emerging with application-specific characteristics. The course is ‘applied’ in nature, and could be offered at the level of B.E/B.Tech IIIrd/ IVth Year, M.Sc IInd/ M.Tech. I Year.

INTENDED AUDIENCE: IIIrd, IVth year B.Tech / M.Sc (Physics/ Electronics/ Electronic Sciences) students, M.Tech Ist Sem students
PREREQUISITES:          Basic undergraduate-level knowledge of Semiconductors, Optics, Electronics and Quantum Mechanics would be required.
INDUSTRY SUPPORT:   Companies and R&D Laboratories working on Laser Applications, Optoelectronic and Optical Communication are expected to value this course.
