Figure 1: Calculated Refractive Index

Caption

Fig. 1 (a) Calculated refractive index and (b) extinction coefficient spectra of Ge with four different porosities (Pr) (0%, 40%, 60% and 75%) as a function of wavelength. (c) Left, schematic view of proposed thin-film coatings with different Pr (i.e. 0%, 40%, 60% and 75%). Right, thin-film structures represented by calculated colors with different Pr (i.e. 0%, 40%, 60% and 75%) at the same thickness of 20 nm. (d) Calculated reflectance spectra of ultra-thin optical coatings (Pr-Ge/Au) with different Pr. (e) Contour plot of reflectance variation for Pr-Ge/Au with four different Pr as a function of Ge thickness (tGe), and of wavelength. White dashed lines in each contour plot indicate variations in the resonance dip. (f ) Color representations from calculated reflectance in (e).
