Integrated photonics plays a critical role in current scientific and technological scene as main platform for the study of fundamental phenomena in Physics, as well as key technology which may be able to overcome the limitations imposed by electronics to the ever increasing need for processing speed and transmission rate in modern computing systems. This PhD project proposes the theoretical and experimental study of coupled microcavities and their applications to optical signal processing, including the development of passive and active devices.
