An optical waveguide for light transmission and a method for creating a master and for generating an optical waveguide therefrom. The waveguide includes a first polymer layer having at least one optical element formed therein, the first polymer layer having an index of refraction of preferably 1.55 or greater, bonded to a second polymer layer, preferably polypropylene, having an index of refraction of preferably 1.50 or less. Since the refractive index of air is approximately 1.0, the first polymer layer is sandwiched between two layers of low refractive index material. The differences between the indices of refraction cause light projected into the polymer layer to be guided in the polymer layer by total internal reflection. Furthermore, once the optical element has been formed in the first polymer layer, it can be used as a master for generating embossments. The embossments are preferably generated by placing liquid polymer in contact with the master, curing it, and separating the cured polymer embossment from the master.
