    • A method for fabricating a hybrid optical integrated circuit having a high-silica glass optical waveguide formed on a silicon substrate, an optical fiber and an optical device coupled optically to the optical waveguide, and an optical fiber guide and an optical device guide on the substrate for aligning the optical fiber and the optical device at predetermined positions, respectively, relative to the optical waveguide. Islands carrying electrical conductors are disposed on the substrate. A first electrical conductor film is formed on the substrate. Second electrical conductor films are formed on the top surfaces of the optical waveguide, the optical fiber guide, the optical device guide and the islands and are electrically isolated from the first electrical conductor film. An electrical conductor member is provided to feed electric power from the first and second electric conductor films to the optical device which needs the power supply. The optical waveguide, the optical fiber guide, the optical device guide and the islands are formed from the same high-silica glass optical waveguide film. Alignment of various portions is facilitated when assembling the circuit. A high coupling efficiency is realized with a low cost.

    • A method of magneto-optically modulating light comprises the steps of linearly polarizing the light on its transmission path, and placing a magneto-optic effect element on the transmission path of the polarized light with the spontaneous magnetization direction of the magneto-optic effect element being substantially parallel with the transmission path. The plane of polarization of the polarized light is rotated about the transmission path in the absence of the magnetic field applied to the magneto-optic effect element having the polarized light pass therethrough. The method further comprises the step of applying the magnetic field to the magneto-optic effect element with its internal magnetization being oriented in a direction perpendicular to the transmission path. The plane of polarization of the polarized light is maintained in its initial state in the presence of the magnetic field applied to the magneto-optic effect element having the polarized light pass therethrough. When the object approaches the magneto-optic effect element, the applied magnetic field is modulated to have the direction of the internal magnetization of the magneto-optic effect element varied. As a result, the plane of polarization of the polarized light is rotated about the transmission path from its initial state when the polarized light passes through the magneto-optic effect element. According to the method, the light can be modulated by way of the object inoperable to apply the magnetic field to the magneto-optic effect element but capable of modulating the magnetic field of the magneto-optic effect element.
    • 磁光调制光的方法包括以下步骤:使光在其传输路径上线性偏振,并将磁光效应元件放置在偏振光的传输路径上,其中磁光效应元件的自发磁化方向为 基本上与传输路径平行。 在没有施加到具有偏振光通过的磁光效应元件的磁场的情况下,偏振光的偏振面绕传输路径旋转。 该方法还包括将磁场施加到磁光效应元件的步骤,其内部磁化在垂直于传输路径的方向上取向。 在施加到具有偏振光通过的磁光效应元件的磁场的存在下,偏振光的偏振面保持在其初始状态。 当物体接近磁光效应元件时,所施加的磁场被调制成具有变化的磁光效应元件的内部磁化方向。 结果,当偏振光通过磁光效应元件时,偏振光的偏振面从其初始状态围绕传输路径旋转。 根据该方法,光可以通过不能操作的物体进行调制,以将磁场施加到磁光效应元件,但是能够调制磁光效应元件的磁场。
