Author Affiliations +
Photonic crystal as the porous silicon multilayer structure was designed and formed. Such structures can be characterized by increased nonlinear optical response due to the weak light localization and could be used to implement all-optical switching. We showed the possibility of the essential photonic band gap edge shift due to a shift of the photonic bandgap edge in the intense laser radiation field due to light self-action effect. All-optical switching in photonic crystals allows to realize logic gates that can be implemented in photonic devices.
