In this paper, we consider a hybrid photonic crystal symmetrically deformed (Bg₅/Cu₃/Bg₅) consisting of the third generation of the copper mean sequence (Cu₃), sandwiched between two Bragg mirrors at the fifth generation (Bg₅). Our system realizes a polychromatic filter that transmits five wavelengths in the visible spectrum independently of the polarization of the light transverse electric or transverse magnetic. Secondly, the photonic crystal (Bg₅/Cu₃/Bg₅) undergoes the deformation y = x^{k + 1} (where k is the degree of deformation, x and y are respectively the coordinates of the system before and after the deformation). With a proper choice of the degree of deformation k, this photonic crystal maintains its property of polychromatic filter whose transmission wavelength is independent of the polarization’s state. Thanks to this deformation, we can disperse the optical windows in different spectra of visible light and exactly in the violet, blue, green, and orange light. This system can be used in the fabrication of color filter devices and the white light emitting diodes.
