Paper Abstract

A critical feature of one-dimensional photonic crystals (omnidirectional reflectors) is an existence of bandgaps where both transverse electric (electric field perpendicular to the plane of incidence) and transverse magnetic (magnetic field perpendicular to the plane of incidence) polarizations of impinging light are totally reflected for any incident angle. In this paper it is shown that omnidirectional bandgaps of binary (two layers in the unit cell) crystals might be increased when each cell is modified by a third layer with the refractive index value in between of the refractive indices of two layers constituting the original cell.
