| Popis: | This present work reports on a study regarding the adjusting intensity transmission optical filters in one-dimensional photonic crystals (1DPCs) with an anisotropic electro optical material (AEO) defect layer. The transmission properties of the proposed PCs in the visible wavelength areas are collected by using the 4 × 4 transfer matrix method. The results show that by embedding the anisotropic layer as a defect, the intensity transmission of optical filters can be affected by alteration of the optical axis of anisotropic layer in the presence of a perpendicular bias voltage. Therefore, due to optical axis dependence of the anisotropic layer, the designed structurer can be used as a novel polarizer, in which the intensity transmission of the optical filter can be controlled and maintaining the working wavelength unchanged. Also, the influence of the variation the incidence angle at the P and S polarization on the tunability transmittance properties are theoretically investigated We can have tunable defect modes, leading to developing a new perspective in the design of new optical devices. |
