The aim of the course was to provide state-of-the-art information in the field of advanced devices for large scale integrated photonics. The course focused on the theory and application of optical microresonators for wavelength selection and routing, for switching and for high-speed modulation. Also materials aspects, design and manufacturing of integrated optics devices based on these resonators for use in optical communication networks were discussed. In particular, micro-ring and micro-disk resonators and photonic bang-gap structures were addressed. At a more fundamental level, some lectures were devoted to promising phenomena that could allow new applications in photonics, such as entangled pairs generation and single quantum dot emission in a cavity.
