I started with just flat silicon with thickness 10 um on top of glass. <\/p>\n<p>First, changing the wavelength range changes the absorption spectrum (as in the figure below: the legend indicates the wavelength range in um). I understand that changing the min wavelength will change the mesh, but how would I know which is more accurate?
