    摘要： Second-order optical nonlinear material arranged on a substrate (10; 21, 22, 23; 50, 51), wherein the second-order optical nonlinear material (14; 24; 45; 52) comprises at least two different materials (A; B; C) arranged in layers on the substrate (10; 21, 22, 23; 50, 51). The layers are arranged on each other in a predetermined order based on the type of material and/or orientation of the layer. The predetermined order is chosen so that the layers of the at least two different materials possess no macroscopic centrosymmetry with respect to their material and/or orientation.

    摘要： The invention provides an optical modulator module (15) by which a dip appearing in a frequency characteristic of a microwave from a DC component to a high-frequency component can be reduced while maintaining the mechanical strength and facilitating handling of a substrate (1) and besides securing the long-term reliability without processing the substrate (1) itself. The optical modulator module (15) includes a substrate (1), an optical modulator (16) including an optical waveguide (2), a signal electrode (3), and a ground electrode (4), and a housing (5) in and to which the optical modulator (16) is accommodated and secured. The shape of a longitudinal section of the housing (5) of the optical modulator module (15) is asymmetrical with respect to a perpendicular line with which the portion of the signal electrode (3) which extends in parallel to the optical waveguide (2) is bisected in the longitudinal direction. The optical modulator module (15) is applied typically to an optical communication system.

    摘要： An electrooptical element is disclosed, made from a crystal (4), for an electrooptical modulator (EOM), for example, a Pockels cell, comprising a housing (5), with the crystal (4) arranged therein in the form of a vertical cylinder, the both end surfaces of which form a front plane, for entry of a light beam and an outlet plane (41), at a separation from the above, with an annular electrode (1) in contact with each of the above and with a retainer, between the housing (5) and both the outer region of the crystal (4) and the two annular electrodes (1). The invention is characterised in that the retainer is embodied as an O-ring (2), concentrically enclosing each annular electrode (1) and forming a closed annular chamber between itself and the housing (5), made from an electrically-conducting material and a hardened sealing compound (3), filling the annular chamber.

    摘要： A travelling wave-type optical modulator (1) has a substrate (3) made of an electro-optic material, optical waveguides (6A,6B) fabricated on the top surface of the substrate, and electrodes (2A,2B,2C) for modulating an optical wave through the optical waveguide. The substrate is partially thinned from the bottom surface of the substrate to form a first thinned portion (3f) and a second thinned portion (3e) so that the thickness of the first thinned portion is set to be larger than the thickness of the second thinned portion, and the optical waveguide is positioned in the first thinned portion.
