FIG. 1.

Schematic of the refractive index profile of two unit cells corresponding to the typical photonic structure studied in this work. Part of width is considered as 21 layers of widths (where is the growth direction of the structure), with refractive indices adjusted to the envelope of a Gaussian function. The refractive indices in part vary from to (indicated as 1 and 2, respectively, in the figure). Part has a width and a constant refractive index (indicated as 3). Each unit cell is separated by the dashed lines.
