عنوان انگلیسی Adjustable three color optical filters using ferroelectric -dielectric generalized heterostructures photonic crystals
چکیده انگلیسی مقاله Abstract: The current research is aimed to investigate the alterations of its opticalfeatures of novel adjustable three color narrowband optical filters, which comprise ofblue, green and red light. A narrowband adjustable transmission optical filters accordingto dielectric- ferroelectric heterostructures photonic structures are designed using thetransfer-matrix method (TMM). The dependence of the ferroelectric refractive index onthe external applied voltage is considered in our investigations. The transmission spectraof the designed hetrostructures with the most valuable parameters, like repeat cyclecounts number of PCs, external electric field, and incident angle for both TE and TMpolarizations are numerically investigated. The results show that the transmission peaksof three color filter shift toward the shorter wavelength by increasing the incident anglefor both polarization. Also, adjustability of the optical features of the proposedhetrostructures crystals external applied electric field is investigated .Therefore, thesecalculated results reveal an innovative idea for designing the tunable trichromatic filterand display applicationsthis.
