Parametric Studies on Artificial Morpho Butterfly Wing Scales for Optical Device Applications

Figure 2

Contour plot of the reflectance spectra of photonic-nanostructures as a function of (a) slab thickness (), (b) air gap thickness (), and (c) slab thickness variation () with fixed total thickness (i.e., ). White dashed lines in (a) and (b) indicate the initial thickness obtained from natural Morpho butterfly.
