Nonlinear Wave Interaction Processes in Photonic Crystals — •Lasha Tkeshelashvili¹, Jens Niegemann¹, and Kurt Busch^1,2 — ¹Institut für Theorie der Kondensierten Materie, Universität Karlsruhe — ²School of Optics/CREOL and Department of Physics, University of Central Florida, Orlando, USA

We show that nonlinear wave interaction processes in Photonic Crystals exhibit certain peculiar properties which originate from the rich photonic band structure of such systems. These include the creation and manipulation of gap solitons in defect-free systems as well as the trapping of solitons at defect sites. In view of applications of these phenomena in all-optical logic elements, we emphasize that the stability of solitary waves in these systems is very important.
