    • A semiconductor integrated circuit including a photoelectric device is provided to reduce a length of an optical waveguide part by installing the optical waveguide part of a thin thickness. A photoelectric device(150) is arranged on a substrate(100). The photoelectric device includes a semiconductor pattern(110). The semiconductor pattern includes an optical waveguide part(106) extended in a first direction and a pair of recessed parts(104) arranged in both sides of the optical waveguide part. The photoelectric device includes a first doped region(112) and a second doped region(114) formed in a pair of recessed parts. A first optical fiber is arranged on a top part of a first grating coupler. A second grating coupler is connected to an output terminal of the photoelectric device.

    • PURPOSE: An optical channel switch for a WDM(Wavelength Division Multiplex) transmission equipment and a control method therefor are provided to increase the flexibility of the operation and structure of a network by adding a switch function to an OADM(Optical Add/Drop Multiplexer) used in the WDM transmission equipment. CONSTITUTION: An optical waveguide combines an input port(411) and an output port(413) with a drop port(412) and an add port(414). A plurality of conductive members(421,422) are allocated on the optical waveguide to be opposite each other. A power supply unit(424) connects each conductive member(421,422) to its each electrode terminal and forms an electric potential difference. A switch element(423) selectively connects and disconnects a power supply path between the power supply unit(424) and the conductive members(421,422).
    • 目的:提供一种用于WDM(波分复用)​​传输设备及其控制方法的光通道开关,通过向OADM(光分插复用器)增加开关功能,增加网络的运行和结构灵活性, 用于WDM传输设备。 构成:光波导将输入端口(411)和输出端口(413)组合成具有分支端口(412)和附加端口(414)。 在光波导上分配多个导电构件(421,422)以彼此相对。 电源单元(424)将每个导电构件(421,422)连接到其每个电极端子并形成电位差。 开关元件(423)选择性地连接和断开电源单元(424)和导电构件(421,422)之间的电源路径。
