OPBG as a function of nmax for the sinusoidal, Gaussian, and Bragg profiles. Panels (a), (b), and (c) correspond to the OT of 24, 25, and 26 μm, respectively. Panels (d), (e), and (f) correspond to the PT = 7.76 μm for three different values of minimum refractive index. The OPBG was computed between 0° and 85° of incidence angle at 99% of the reflectivity.
