    摘要： The present invention relates to a transparent electrode comprising an ultra thin metal conductor (2) with a thickness between 1 nm and 10 nm and a metal grid in contact with the ultra thin metal conductor (3), the metal grid comprising openings. The invention relates also to a method for its manufacture. It can be applied in, for example, optoelectronic devices. Thanks to the metal grid, the sheet resistance of the electrode can be lowered without compromising the transparency of the electrode.

    摘要： Accordingly, a preferred embodiment of the present invention comprises an electro-optical device having an optical waveguide that includes two optical pathways, wherein the optical waveguide is embedded within the substrate. A bias electrode layer is formed on the surface of the substrate. A buffer layer is formed on at least a portion of the bias electrode layer and the surface of the substrate. An RF electrode layer is formed on the buffer layer. A bias-tee electrically couples the bias electrode layer and the RF electrode layer.

    摘要： A method and structure are disclosed with a simplified approach for fabricating a LiNbO3 wafer with Ti indiffusion wafeguide on the surface that is domain inverted. The method involves indiffusing Ti into LiNbO3 with a predefined temperature and time indiffusion range, a Li enriched and dry oxygen atmosphere, which allows making optical waveguides on the z− crystal face without any significant domain inversion occurring on the z+ face of the crystal. This allows for subsequent poling without the need of any additional removal of the thin domain inverted layer which would otherwise appear on the z+ face. Even in instance where a thin domain inversion layer is formed, it is insufficient thick to prevent poling, eliminating the need for the grinding process.

    摘要： A coplanar integrated optical waveguide electro-optical modulator comprises a substrate (1) of an electro-optic material, at least two optical waveguides (41, 42) integrated in the substrate in correspondence of a surface (71) thereof, and an electrode system (80, 90, 100; 80, 90, 900; 12-15; 120, 130, 140, 150, 160, 170) arranged on the surface for applying a modulating electric field to the waveguides suitable for causing a modulation of a refractive index of the two waveguides in a device modulation region (50). The waveguides are formed, for at least a section thereof (411, 421) in the device modulation region, in respective substrate regions (61, 62) which have electro-optic coefficients of opposite sign along an axis transversal to the waveguide sections, so that a modulating electric field of same direction and orientation in the waveguide sections causes refractive index modulations of opposite sign in the waveguide sections. Chirp-free coplanar waveguide modulators and single-drive double coplanar strip modulators can thus be obtained.
