PHYSICS

Students should acquire the fundamentals of Applied Optics and different skills and abilities in this area. Understanding these basics will allow them in turn to acquire the skills necessary to apply the optical models to simple problems resolution. In particular, those corresponding to wave optics, geometrical optics and quantum optics (light as photons accumulation). At the completion of this topic, students must understand the basic phenomena involved in the interaction of light and matter, their dependence on the wavelength and the properties involved in the generation, transmission and detection of light. Also students must understand the basics of the huge number of applications based on optics and photonics. 3D vision, micro and nano technologies in optics, infrared vision, remote sensing, scientific understanding of global warming,... Finally, after acquiring a well-founded basic knowledge, the students also acquire the ability of understanding and using future developments and further applications arising in the changing world of Photonics.

-In the lectures the theoretical concepts previously described, will be discussed. - Given the advanced nature of the subject, when methodologically appropriate, problems solving and questions, similar to those of the exams, in order to: Identify the more important Optics and the light-matter interaction laws involved. Analyze the logic of the result obtained: orders of magnitude, relate the most important conclusions to other scientific and technological subjects involved in advanced optics - Tutorial sessions will be schedule throughout the course, available to students at will. These sessions must be requested in advance
