Introduction In the chapter, we give results of investigation of dynamics of linear and nonlinear photonic crystals (PhC). It is well-known fact that modern semiconductor electronic data processing systems are experiencing fundamental problems with further improvement of the microprocessors productivity. One of the alternative ways is to use hybrid or all-optical circuits on the basis of PhCs. The heart of such all-optical circuit is nonlinear PhC which may provide the basis for logic, memory cells, switching, local routing, power limiters, isolators, etc. Therefore, it is of crucial importance to understand the processes taking place in such components and optimize their characteristics. One of the most important points of view to the PhCs is their interaction with short and ultra-short pulses which may limit the productivity of an optical circuit. Recently, there have been proposed a great number of PhC components bases on different operating principles. However, being resonant-transmitting structures, PhCs themselves reduce the possibility to work with ultra-short pulses. In the papers of the authors, it have been proposed to use wideband PhC filters instead of high-Q ones [9], [6]. Lower resonant properties as compared to high-Q filters, allow to reduce distortion of the signal passing through such filters. In this chapter we present the investigation results and analysis of the temporal response of different kinds of wideband PhC filters. Namely, we consider filters made of linear optical materials which can be used for local multiplexing and routing and the ones made of nonlinear optical materials which properties strictly depend on the radiation intensity. © 2013 Guryev et al.; licensee InTech.
