Enhanced visible light transmission in a one-dimensional hybride graphene-photonic crystal structure

In this paper, we have theoretically investigated and optimized one dimensional hybride graphene-photonic crystal structure (1D-HGPCS) for enhancing visible light transmission. We adopted transfer matrix method to calculate transmission spectrum. Different combination styles to form 1D-HGPCS and the effects of structural parameters such as number of layers, thickness, permittivity and chemical potential have been studied for different states of polarization, TE and TM, in details. Room temperature optimum values have been obtained for blue-green-red light transmission. Our numerical approach creates promising tool for tuning 1D-HGPCS as long as considering graphene benefits, to enhance light extraction efficiency in white LEDs.
