The current research is aimed to investigate the alterations of its optical
features of novel adjustable three color narrowband optical filters, which comprise of
blue, green and red light. A narrowband adjustable transmission optical filters according
to dielectric- ferroelectric heterostructures photonic structures are designed using the
transfer-matrix method (TMM). The dependence of the ferroelectric refractive index on
the external applied voltage is considered in our investigations. The transmission spectra
of the designed hetrostructures with the most valuable parameters, like repeat cycle
counts number of PCs, external electric field, and incident angle for both TE and TM
polarizations are numerically investigated. The results show that the transmission peaks
of three color filter shift toward the shorter wavelength by increasing the incident angle
for both polarization. Also, adjustability of the optical features of the proposed
hetrostructures crystals external applied electric field is investigated .Therefore, these
calculated results reveal an innovative idea for designing the tunable trichromatic filter
and display applicationsthis
