Abstract : This research synopsizes study and measurement of a films efficiency manufactured by Pyrromethene dyes doped in silica/polymeric nano-composite media in order to do as diffraction grating by Michelson interferometer using two laser beams as writer and reader beam. When the samples incur two interfered laser writer beams, spatial change for photonic properties will happen in interference area according to photochemical reaction between laser beam and the samples. Then, a diffraction grating will happen unless the laser beam stops. The incurrence of samples to laser beams will lead to absorb the beam that increase in time. Otherwise, when the concentrations increase, the absorption increases with time up to saturation stage at long periods for high concentration. This means the grating efficiency go up with increasing incurrence. According to these results, we can expect that index of refraction will reach to maximum value at the peak of grating efficiency.
