    • PROBLEM TO BE SOLVED: To reduce return light to a first optical path in an optical component that adjusts an optical power propagating from the first optical path to a second optical path. SOLUTION: A variable light optical attenuator 100 is equipped with an optical path 26 having an optical axis 16, an optical path 27 having an optical axis 17, and a mirror 21 that moves in directions 32, 33 crossing the bisector 18 of an angle formed by the optical axes 16, 17. On the surface of the mirror 21, there is provided a reflection part 21a that, upon receiving light from an optical path 11, reflects the light to an optical path 12. The reflection part 21a is provided with an edge 21b including a straight line section arranged on a plane substantially vertical to the bisector 18. The straight line section is tilted to the normal of a plane including the optical axes 16, 17. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:为了减少调整从第一光路传播到第二光路的光功率的光学部件中的第一光路的返回光。 解决方案:可变光衰减器100配备有具有光轴16的光路26,具有光轴17的光路27和沿着与二等分线18交叉的方向32,33移动的反射镜21 由光轴16,17形成的角度。在反射镜21的表面上设置有反射部21a,其在从光路11接收光时将光反射到光路12.反射部21a 设置有包括布置在基本上垂直于平分线18的平面上的直线部分的边缘21b。直线部分倾斜到包括光轴16,17的平面的法线。(C) 2005年,JPO&NCIPI

    • A method and apparatus for communications according to various aspects of the present invention comprises a switching system configured to receive optical signals and direct the optical signals along a selected optical path. The switching system suitably includes more than one switch, and at least one of the switches may include a variable refractive material having a first state and a second state, wherein the optical signal is transmitted via a first path when the variable refractive material is in the first state and the individual channel signal is transmitted via a second path when the variable refractive material is in the second state. The switching system may alternatively or additionally include a switch element having a reflective state and a transmissive state, wherein the optical signal is reflected via a first path when the switch element is in the reflective state and the individual channel signal is transmitted via a second path when the switch element is in the transmissive state.
