      I’m doing simulation on Silicon wafer. Do we have to set input plane for a fixed wavelength such as 550 nm etc for every materials? OR can we set up input plane for whole a visible spectrum? How To set such input plane so that part of it absorb by silicon which will reflect in its spectra. The power spectrum plots only relative power Vs distance. How to get reflectance/absorbance and refractive index spectra Vs. wavelength from the such graph or if any other way is their to get it.

      Hi Sandeep,

      You can look at the power vs frequency by using the export tool in 32 bit version of OptiFDTD. You can find a tutorial in your installation directory and I have also attached it here called Getting Started.

      Let me know if this helps.
