title: Analysis of defect layers' insertion effect on optical transmission properties of multilayer structures based on one-dimensional photonic crystals.
abstract: In this paper, we are interested in the analysis of the transmission spectrum of several multilayer structures based on one-dimensional photonic crystals (1D PCs) infiltrated with different kinds of defect materials, such as bismuth oxide (Bi2O3), lithium niobate (LiNbO3), and E7 liquid crystal (LC). A 1D PC acting as a multichannel filter is constructed by inserting multiple Bi2O3 defect layers, while a localized mode is moved by applying various electric fields on a LiNbO3 defect layer inserted in the middle of a 1D PC structure used as a tunable device. A localized mode is also tuned by applying different magnetic fields on an E7 LC phase shifter inserted between SiO2/TiO2 alternative layers.
