| 402-0464-00L | Optical Properties of Semiconductors | 8 credits | 2V + 2U | G. Scalari, T. Chervy | |
| Abstract | This course presents a comprehensive discussion of optical processes in semiconductors. | ||||
| Objective | The 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. | ||||
| Content | Electronic states in III-V materials and quantum structures, optical transitions, excitons and polaritons, novel two dimensional semiconductors, spin-orbit interaction and magneto-optics. | ||||
| Prerequisites / Notice | Prerequisites: Quantum Mechanics I, Introduction to Solid State Physics | ||||
| 402-0465-58L | Intersubband Optoelectronics | 6 credits | 2V + 1U | G. Scalari | |
| Abstract | Intersubband 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". | ||||
| Objective | The 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. | ||||
| Content | The 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 notes | The reference book for the lecture is "Quantum Cascade Lasers" by Jerome Faist , published by Oxford University Press. | ||||
| Literature | Mostly the original articles, other useful reading can be found in: -E. Rosencher and B. Vinter, Optoelectronics , Cambridge Univ. Press -G. Bastard, Wave mechanics applied to semiconductor heterostructures, Halsted press | ||||
| Prerequisites / Notice | Requirements: A basic knowledge of solid-state physics and of quantum electronics. | ||||
