In the present communication, we have theoretically in- vestigated and studied the re∞ection properties of one-dimensional birefringent-dielectric photonic crystal (1D BDPC) structure consist- ing alternate layers of BD material. From the analysis of the re∞ectance spectra it is found that 100% re∞ection region for both TE- and TM- mode can be enhanced signiflcantly in comparison with 1D dielectric- dielectric photonic crystal (DDPC). In order to obtain the re∞ection spectra of the proposed structure we have used the transfer matrix method (TMM). The structure proposed by us, has a wider omni- directional re∞ection (ODR) range in comparison to conventional all dielectric photonic crystals (PCs). The width of ODR can be enlarged by considering the suitable choice of lattice parameters.
