Syllabus
Obiettivi Formativi
The aim of the first part of the course (Quantum Electronics) is to give a correct quantum-mechanical description of the radiation-matter interaction and provide the physical tools necessary to understand the functioning of LASERs. At the end of the module, the students should possess the main aspects of the radiation-matter interaction and should be able to qualitatively and quantitatively describe the functioning of a LASER oscillator. The subject of the second part of the course (Nonlinear Optics) is the description of nonlinear interaction of laser with matter aimed to the understanding of the working principles of integrated optical devices performing wavelength conversion, modulation, and logical functions. The applications of nonlinear optics to information technology, environmental monitoring, and biomedical sciences are also treated.
Prerequisiti
The Mathematical and Physical concepts given by the 1st Level Degree (Mechanics and Electromagnetism, Geometry and Algebra). The concepts illustrated in the course of “Fotonica” (Photonics) are important but not essential.
