Abstract

Poly[5,7-dodecadiyn-1,12-diol-bis(n-butoxycarbonyl-methyl-urethane)], or poly-4BCMU, thin films permanently bleach when irradiated with light in the absorption band. The resulting decrease in refractive index has been measured and is sufficient to allow formation of waveguide channels and gratings. The optical properties of the bleached material are discussed. A waveguide grating coupler is fabricated by periodic bleaching and demonstrated.
