Summary

Series of lectures covering the optical properties of direct bandgap semiconductors including processes such as absorption, spontaneous and stimulated emission; the physics of heterostructures and the properties of the main light emitting devices that are light-emitting diodes and laser diodes.

Content

1. Semiconductor materials for optoelectronics

2. Light-matter interaction in semiconductors

3. Nanostructures and microcavities

Growth techniques, quantum wells, superlattices, quantum dots, microcavities, Purcell effect

4. Electroluminescence

Light-emitting diodes, quasi-Fermi levels, emission spectra, efficiency, radiative and nonradiative lifetimes

Applications for displays and solid-state lighting

5. Laser diodes

Stimulated emission, optical gain, transparency and threshold currents, spectral characteristics, far-field and near-field emission patterns, efficiency, waveguides

Fabry-Perot laser diodes, distributed feedback and vertical cavity laser structures

Bandgap engineering, quantum well laser diodes, separate confinement heterostructures
