Course Content
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.

Learning Outcomes

Algemene competenties

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

Grading

The final grade is composed based on the following categories:
Oral Exam determines 55% of the final mark.
Written Exam determines 10% of the final mark.
PRAC Teamwork determines 10% of the final mark.
PRAC Presentation determines 25% of the final mark.

Within the Oral Exam category, the following assignments need to be completed:

  • exam with a relative weight of 100 which comprises 55% of the final mark.

    Note: Oral examination with opern book consulting
    At the end of the academic year
    - an oral examination, prepared in a written way with a minimum of 55% of the grand total(2/3) with open book will be organized.

Within the Written Exam category, the following assignments need to be completed:

  • Writtem exam with a relative weight of 100 which comprises 10% of the final mark.

    Note: Examination in the form of exercises with open book consulting

Within the PRAC Teamwork category, the following assignments need to be completed:

  • Joint report of groups work with a relative weight of 100 which comprises 10% of the final mark.

    Note: Final report of the groups work of an assignment of topics related to part 1 of the course held during the year

Within the PRAC Presentation category, the following assignments need to be completed:

  • Discussion of groups work with a relative weight of 100 which comprises 25% of the final mark.

    Note: The final report will be evaluated during an oral discussion with open book consulting

Additional info regarding evaluation

At the end of part 1 of the course a project will be worked out by the students to get better insights into the concepts of the course. The final report of this assignment will be evaluated during an oral discussion. A partial exemption can be obtained about this part of the theory can be obtained.

At the end of the academic year

- an oral examination, prepared in a written way within open book format will be organized.

- additionally an exercise exam within an open book format, will be organized the same day
