We have investigated the probing beam transmittance due to the photon-induced anisotropy effect in the bacteriorhodopsin/polymer composite film (bR/PC film) by using the probing-pumping beam method under different laser wavelengths. By using a theoretical simulation, we give the characteristics of the birefringence $Delta n$ and the dichroism $Delta D$ for various wavelengths of the probing and the pumping beams.

Keywords: Photo-induced anisotropy, Birefringence, Dichroism
