CPM SeminarDiscrete Optical SolitonsRoberto MorandottiINRS-EMTThe study of optical solitary phenomena is important for both physics and engineering. In particular, the ability of solitons to retain their shape and to interact makes them ideal bits for all optical telecommunication systems. Ultra fast Kerr solitons have been demonstrated in the time domain (temporal solitons) and in the space domain (spatial solitons). More recently, a special class of spatial solitons (propagating in a periodical optical potential) has shown even more fascinating characteristics. Discrete solitons (DS) were first proposed in the late 80s by Christodoulides et Al., and demonstrated by us in 1998. We found that DSs present novel dynamical behaviours, two signs of diffraction, and are subjected to a photonics band gap-like structure. The peculiar characteristics of discrete solitons, together with our most recent results, will be discussed.
