Optical waveguides fabricated in anodic alumina films.
The transmittance of an anodic alumina film changes significantly with the refractive index of the guest material that is contained in columnar pores. We fabricated a channel waveguide with a Y junction in an alumina film by filling the pores with photocurable resins of suitable refractive indices.
