Tunable all-optical switching in periodic structures with liquid-crystal defects

Miroshnichenko, Andrey; Pinkevych, Igor; Kivshar, Yuri


We suggest that tunable orientational nonlinearity of nematic liquid crystals can be employed for all-optical switching in periodic photonic structures with liquid-crystal defects. We consider a one-dimensional periodic structure of Si layers with a local defect created by infiltrating a liquid crystal into a pore, and demonstrate, by solving numerically a system of coupled nonlinear equations for the nematic director and the propagating electric field, that the light-induced Freedericksz...[Show more]
