Nanostructured Porous Silicon Photonic Crystal for Applications in the Infrared
Figure 3
2D calculated PBS for a structure based on a square mesh of dielectric veins with a width of , with the dielectric material being a PSi layer with 40% porosity (). Bands are plotted along high-symmetry lines of the Brillouin zone, where frequency is given in normalized units (). The representation of 2D Brillouin zone and the schematic representation of 2D structure used for the calculations are shown in the inset of PBS.
