Aanbieding 1 met studiegidsnummer 4017333FNR voor alle studenten in het 2e semester met een gespecialiseerd master niveau.
This course is taught at UGent. See https://studiegids.ugent.be/2020/EN/studiefiches/E030782.pdf
The course is divided into three parts
part 1: Physics of semiconductors for photonic applications including
Overview of optoelectronics, advanced theory of band structures, Quantum confined semiconductor structures including strain, phonons in semiconductors, optical processes in semiconductors
part 2: Technologies: advanced crystal growth and epitaxial techniques, integration and packaging technolgies
part 3: Devices: photodetectors, light sources, light modulators,and miscellaneous devices
For all parts exercises and independent work will be organised
Overview of the basic properties of semiconductirs, comparitive study between a whole set of semiconductors (binary, ternay and quaternary compounds).
Electron wave function in semiconductors: derivation of the dispersion relations in the conduction and valence band based on the k.p approximation
Heterostructures: boundary conditions, lattice matched and pseudomorphic structures, quantum wells, wires and dots based on the envelope function approximation
Phonons in semiconductors: acoustic, optical, transverse and longitudinal
Optical transition in semiconductors based on the Fermi's Golden Rule: absorption processes in direct and indirect semiconductors, interband and intraband transitions intervalley and intravalley, free carrier absorption, phononabsorption.
Technological overview of typical advanced technological processes and photonic integration techniques.
Photonic devices:
light sources: LEDS and lasers: gain, non-parabolic effects, strain,...
detectors: o.a. photoconductors, PN, PIN and avalanche photodiodes , Metal-Schottky, Quantum Well IR detectors, Quantum Dot IR detectors, Thermal photodetectors, Seebeck detectors
modulators, o.a. electro-absorption modulators, quantum confined Stark effect
Exercises aim to get the student more familiar with the theoretical concepts of the course.
Course is lectured in the second semester. Lecture take place in University of Ghent (UGent).

The student will acquire an advanced theoretical framework (mathematical and quantum-mechanical tools) to design optoelectronic devices. He will get insight in the band structures of semiconductors and how they change in structures with reduced dimensions. He will get insights in the newest technologies to develop novel devices for the future. He will know the operation principles of a large set of photonic devices such as detectors, light sources, modulators and others.
The course will be a solid base to understand the operation of optoelectronic devices of today, and will be able to design novel devices for future based applications
