402-0464-00LOptical Properties of Semiconductors8 credits2V + 2UA. Imamoglu, G. Scalari
AbstractThis course presents a comprehensive discussion of optical processes in semiconductors.
ObjectiveThe rich physics of the optical properties of semiconductors, as well as the advanced processing available on these material, enabled numerous applications (lasers, LEDs and solar cells) as well as the realization of new physical concepts. Systems that will be covered include quantum dots, exciton-polaritons, quantum Hall fluids and graphene-like materials.
ContentElectronic states in III-V materials and quantum structures, optical transitions, excitons and polaritons, novel two dimensional semiconductors, spin-orbit interaction and magneto-optics.
Prerequisites / NoticePrerequisites: Quantum Mechanics I, Introduction to Solid State Physics
402-0465-58LIntersubband Optoelectronics6 credits2V + 1UJ. Faist, G. Scalari
AbstractIntersubband transitions in quantum wells are transitions between states created by quantum confinement in ultra-thin layers of semiconductors. Because of its inherent taylorability, this system can be seen as the "ultimate quantum designer's material".
ObjectiveThe goal of this lecture is to explore both the rich physics as well as the application of these system for sources and detectors. In fact, devices based on intersubband transitions are now unlocking large area of the electromagnetic spectrum.
ContentThe lecture will treat the following chapters:
- Introduction: intersubband optoelectronics as an example of quantum engineering
-Technological aspects
- Electronic states in semiconductor quantum wells
- Intersubband absorption and scattering processes
- Mid-Ir and THz ISB Detectors
-Mid-infrared and THz photonics: waveguides, resonators, metamaterials
- Quantum Cascade lasers:
-Mid-IR QCLs
-THZ QCLs (direct and non-linear generation)
-further electronic confinement: interlevel Qdot transitions and magnetic field effects
-Strong light-matter coupling in Mid-IR and THz range
Lecture notesThe reference book for the lecture is "Quantum Cascade Lasers" by Jerome Faist , published by Oxford University Press.
