Figure 1

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