# Complex Index of Refraction of Silicon

| Here is the complex index of referaction of Silicon (from Handbook of Optical Constants of Solids (E.D. Palik))
|  | Note that the imaginary part k increases as soon as the wavelength is small enough for band-to-band absorption processes; i.e. h · n > EG applied (with EG = band gap).
