Learning outcomes / competencies
Students will gain core interdisciplinary knowledge in the field of electronics and photonics towards realizing modern Terahertz systems. Students will acquire the fundamental understanding of the working principles of the electronic-photonic devices and are able to describe them quantitatively. After the successful completion of the course, students will be able to apply concepts in developing industrial terahertz systems.
Content
This course is divided into the following five sections.
- Building blocks of THz frequency synthesis:
Rectification process and its implications on electronic and photonic transport properties;
Fourier analysis of rectification, Semiconductor band structure introduction, artificial bandgap nano-engineering in generated semiconductor heterostructures, electron transports (junction, interband-, intraband-, intersubband- transitions), introduction to transistors and their multi-functions. - Principles of Terahertz generation:
Electronic sources – Transistors as a THz frequency synthesizer -> harmonic generators, oscillators;
Photonic sources – THz lasing in semiconductor heterostructures -> quantum cascade lasers;
Optoelectronic source – THz photomixing. - Principles of Terahertz detection:
radiation coupling, Terahertz wave propagation, detector figures of merits, direct detection, heterodyne detection. - Defining Terahertz systems specifications:
broadband vs narrowband, active vs passive, frequency domain vs time domain, coherent vs incoherent,
power vs field, far-field vs near-field, Terahertz Imaging examples, Terahertz spectroscopy examples, Terahertz communications examples.
