Abstract: An electro-optic device, comprising an insulating layer and a layer light-carrying material adjacent the insulating layer. The layer of light-carrying material, such as silicon, comprises a first doped region of a first type and a second doped region of a second, different type abutting the first doped region to form a pn junction. The first doped region has a first thickness at the junction, and the second doped region has a second thickness at the junction, the first thickness being greater than the second thickness, defining a waveguide rib in the first doped region for propagating optical signals. Since the position of the junction coincides with the sidewall of the waveguide rib a self-aligned process can be used in order to simplify the fabrication process and increase yield.

Abstract: An optical coupler comprises an input waveguide, an intermediate waveguide, an output waveguide, a first grating situated between the input and intermediate waveguides, and a second grating situated between the intermediate and output waveguides such that, in use, light propagating in the input waveguide is coupled into the intermediate waveguide with the assistance of the first grating, and thence is coupled into the output waveguide with the assistance of the second grating. The coupler is a directional coupler, in particular a dual grating-assisted directional coupler, and may be used to couple light between an optical fibre and an integrated semiconductor device, or between dissimilar waveguides.

Abstract: Butane-1,4-diol, gamma-butyrolactone or tetrahydrofuran are prepared by vapor phase hydrogenation of a C4-dicarboxylic acid derivative. A maleic anhydride containing vapor stream is contacted in an absorption zone with a first high boiling solvent. A waste gas stream is passed to a scrubbing zone containing a second, higher boiling solvent. The waste gas is purged and the first and second solvents are recovered and recycled. Maleic anhydride is obtained from the absorption zone and converted to a maleic acid diester, which is stripped from the first solvent with hydrogen. The desired products are obtained by hydrogenation.
