Abstract | Classical and semi-classical introduction to Quantum Electronics. Mandatory for further elective courses in Quantum Electronics. The field of Quantum Electronics describes propagation of light and its interaction with matter. The emphasis is set on linear pulse and beam propagation in dispersive media, optical anisotropic materials, and waveguides and lasers. | ||||

Learning objective | Teach the fundamental building blocks of Quantum Electronics. After taking this course students will be able to describe light propagation in dispersive and nonlinear media, as well as the operation of polarization optics and lasers. | ||||

Content | Propagation of light in dispersive media Light propagation through interfaces Interference and coherence Interferometry Fourier Optics Beam propagation Optical resonators Laser fundamentals Polarization optics Waveguides Nonlinear optics | ||||

402-0468-15L | Nanomaterials for PhotonicsDoes not take place this semester. | 6 credits | 2V + 1U | R. Grange | |

Abstract | The lecture describes various nanomaterials (semiconductor, metal, dielectric, carbon-based...) for photonic applications (optoelectronics, plasmonics, ordered and disordered structures...). It starts with concepts of light-matter interactions, then the fabrication methods, the optical characterization techniques, the description of the properties and the state-of-the-art applications. | ||||

Learning objective | The students will acquire theoretical and experimental knowledge about the different types of nanomaterials (semiconductors, metals, dielectric, carbon-based, ...) and their uses as building blocks for advanced applications in photonics (optoelectronics, plasmonics, photonic crystal, ...). Together with the exercises, the students will learn (1) to read, summarize and discuss scientific articles related to the lecture, (2) to estimate order of magnitudes with calculations using the theory seen during the lecture, (3) to prepare a short oral presentation and report about one topic related to the lecture, and (4) to imagine an original photonic device. | ||||
