Optically inscribed surface relief diffraction gratings on azobenzene-containing polymers for coupling light into slab waveguides

Surface relief diffraction gratings inscribed on azobenzene-containing polymers are designed to act as light couplers into slab waveguides. The gratings are inscribed both directly in poly{4-[2-(methacryloyloxy)ethyl]azobenzene} (pMEA) waveguide material, and in an azopolymer cladding layer applied...

Description
Summary:Surface relief diffraction gratings inscribed on azobenzene-containing polymers are designed to act as light couplers into slab waveguides. The gratings are inscribed both directly in poly{4-[2-(methacryloyloxy)ethyl]azobenzene} (pMEA) waveguide material, and in an azopolymer cladding layer applied to polyimide, silicon nitride, and silicon oxynitride films. Input and output coupling of both 633 and 830 nm light is observed in the waveguides.
