Abstract

The theory of second-harmonic-generated radiation (SHGR) from a chiral sculptured thin film (STF) for bio-sensing is presented. Linear emission (LE) is supposedly due to luminescence-producing bio-reactions occurring in the void regions of the chiral STF platform. The associated linear electromagnetic fields generate a nonlinear source polarization field in the material that the platform is made of, provided the material has significant nonlinear properties in an appropriate wavelength-regime. Information contained in the polarization state of SHGR could either supplement information gleaned from LE or be useful just by itself.
