    摘要： There is provided a hybrid mounted device that includes a element such as semiconductor laser diode (LD), and a board such as a silicon platform having formed thereon an optical waveguide. The LD is mounted to the silicon platform, and is optically coupled to the optical waveguide. The mounting position of the LD is determined by positioning first alignment marks formed on the board and second alignment marks formed on the LD. In this configuration, initial positional deviation amount measuring marks that can measure the initial positional deviation amount of the first alignment marks themselves are formed on the board. The mounting position of the is corrected to a position where the second alignment marks are shifted with respect to the first alignment marks according to the initial positional deviation amount measured from the initial positional deviation amount measuring marks.

    摘要： An optical waveguide includes a substrate in the shape of a flat plate; lower clad that is disposed on the substrate; and a core that is disposed on the lower clad and transmits light. The optical waveguide includes a first optical waveguide and a second optical waveguide. The first optical waveguide includes a first core on the lower clad, and is disposed so as to extend along a direction in which the light travels to a first position. The second optical waveguide includes a second core on the lower clad, is disposed so as to extend along a direction in which the light travels to a second position, and has a lower relative refractive index difference than the first optical waveguide. The first optical waveguide and the second optical waveguide form, between the first position and the second position, a layer structure where the first core and the second core are disposed such that the first core is positioned a predetermined distance away from the second core in a direction perpendicular to the substrate. At least either the first optical waveguide or the second optical waveguide includes a mode coupling section and a mode conversion section. The mode coupling section includes a directional coupler to conduct the mode coupling of the first core and the second core between the first position and the second position. The mode conversion section is connected to the mode coupling section, and has a tapered core structure to adjust the mode diameter of the first core to the mode diameter of the second core.

    摘要： A core for propagating optical signals, and a pair of first and second cladding layers disposed opposite each other, between which the core is disposed, are provided. The first cladding layer on which the core is formed has a multilayer film on the boundary face side contacting the core, and the multilayer film has a multilayer structure in which a distortion stress exists among multiple materials. With such a configuration, light scattering is prevented at the boundary between the cladding and the core, and the polarization dependency is also reduced.

    摘要： A pair of upper and lower semiconductor switching elements can switch between the conductive state and the non-conductive state when control voltages vary. A controller controls the levels of the control voltages to alternately turn on the upper and lower semiconductor switching elements. The controller controls the absolute value of the second control voltage of the lower semiconductor switching element so as to reach a mean voltage before and after the time of transition between the conductive state and the non-conductive state of the upper semiconductor switching element. The mean voltage is lower than the absolute value of a threshold voltage and higher than a reference voltage.
