Obiettivi dell'insegnamento

Photonics is emerging in various areas of communications, electronics and sensors to support the need for transparency, speed, and ability to handle huge data streams and multiplexing, as request from the evolution of communication systems today. The course examines in detail the integrated optics sector, focusing on theoretical, technological and applicative aspects. We discuss various issues related to the perspective of photonics technologies, the actual and future markets and potentialities, the generic foundry scheme and, in detail, down to photonics devices: waveguides, passive devices such as filters and (de)multiplexers, modulators, integrated lasers and photodetectors, amplifiers and technologies and materials. When communications occur on very small scales as inside electronics chip, chip-to-chip or board-to-board then it comes to optical interconnects, an emerging field that will be the lifeblood of the future high speed electronic.
