摘要： An acoustic-optical device for optical filtering includes two successive acoustic-optical interaction segments separated by an intermediate polarizer and each modifying the polarization of light guided by it. The modification depends on the frequencies of the interacting optical and acoustic waves. The acoustic waves are supplied symmetrically to the two interaction segments from a common electro-optical transducer. The transmission spectrum of the optical filter is subject to apodization by coupling between an auxiliary acoustic waveguide including the transducer and a main acoustic waveguide including the optical waveguide. Applications of the device include fiber optic telecommunication systems.

摘要： In a method for fixing a polarization-preserving optical fiber the fiber is illuminated transversely and orientation of the polarization-preserving plane of the fiber is monitored by direct visual examination of internal components of the fiber rendered visible by such illumination. The illumination is effected through the wall of a transparent ferrule holding the fiber. The method has applications in fiber optical telecommunications systems.

摘要： A semiconductor optical component is disclosed which comprises a current injection region and at least one electrically isolated region referred to as a first plateau, each region containing a contact layer of an alloy based on gallium arsenide, GaAs, deposited on a semiconductor material upper confinement layer. The component further comprises in the first plateau a dielectric material isolation layer on top of the contact layer. An attachment layer is disposed between the contact layer and the isolation layer to increase the adhesion of the isolation layer to the contact layer. A method of fabricating the above kind of component is also disclosed.

摘要： A method of fabricating a component having a crystalline silicon substrate includes the steps of depositing a layer of silica onto a crystalline silicon substrate, this silica layer being doped with dopants, and then treating the substrate. Before the doped silica layer is deposited, a barrier layer is formed on the substrate, consisting of a barrier material opposing diffusion of the dopants. The doped silica layer is deposited onto this barrier layer. The invention finds one particular application in connecting flat bundles of fibers in communication networks.
