The Abdus Salam International Centre for Theoretical Physics (ICTP), in collaboration with the International Commission for Optics (ICO), the Optical Society of America (OSA), the International Society for Optics and Photonics (SPIE), the European Optical Society (EOS), the Societa Italiana di Ottica e Fotonica (SIOF), the US National Academy of Sciences (NAS), and the International Society on Optics Within Life Sciences (OWLS) will organize a Winter College on Optics: Fundamentals of Photonics - Theory, Devices and Applications, which will be held at ICTP, Trieste, Italy, from 10 to 22 February, 2014. The Winter College consists of four parts. The first one presents foundations of electromagnetic optics, optical waveguides and photodetectors. The second part is dedicated to integrated optics theory, photonic circuits design, numerical simulations, special sources for integrated optics ending with special dedication to photonic materials, assembling and packing techniques. The third part of the course will be dedicated to technological applications of waveguide platform and optoelectronic circuits. Finally, the fourth part concentrates in particular photonics devices, non-linear photonics and plasmonics and ending with applications of photonics in biomedicine and renewable energy.
