ABSTRACT:
Disclosed herein is a flexible film optical waveguide, which is in flexible film form and includes upper and lower cladding layers, each of which is formed of an organic-inorganic hybrid material, and a core layer provided between the upper and lower cladding layers and formed of an organic-inorganic hybrid material having a refractive index higher than that of the organic-inorganic hybrid material of each of the upper and lower cladding layers. In addition, a method of fabricating such a flexible film optical waveguide is also provided.
