Popis:	This paper demonstrates for fabricating the biopolymric optical planar waveguide. Gelatin and chitosan were mixed with ratio of 9 to 1 and stirred at 70°C with 1300 rpm. The blended biopolymer was spincoated on silicon substrate with 500 rpm and then dried in the oven at 50°C. The refractive indices of the prepared biopolymer clad and core layers of the waveguide were measured by the ellipsometry. The measured refractive indices of the two layers were obtained to be 1.516 and 1.52, respectively. The nanograting was successfully imprinted on surface of the biopolymeric waveguide.
