    • A high isolation optical switch has a core surrounded by a clad layer. The core is shaped to have an input line and two output lines branching off from the input line through a node. Two heater elements are each disposed adjacent to each of the two output lines. One of the heater elements is selectively energized to heat one of the output lines to lower the refractive index thereof to such an extent as to make that output line inactive. The two output lines are each shaped to include a straight segment that branches off from the node. Each heater element includes a main strip that overlaps partially with the straight segment of the adjacent output line with respect to a horizontal projection plane on which the heater elements and the core project, and also includes a deflector strip that extends from the main strip along the node. Each of the deflector strips runs in a spaced relation with the node and in a generally parallel relation with an extension line of the straight segment of the non-associated output line with respect to the horizontal projection plane. The deflector strip acts to heat a part of the node leading to an inactive output line but to keep the other part leading to an active output line from being thermally unaffected, thereby deflecting the light out through the node for successfully directing it into the active output line.
    • 高隔离光开关具有被覆层包围的芯。 芯体成形为具有通过节点从输入线分支的输入线和两条输出线。 两个加热器元件分别设置成与两条输出线中的每一条相邻。 加热器元件中的一个被选择性地通电以加热输出线中的一个以将其折射率降低到使输出线不活动的程度。 两个输出线各自被成形为包括从节点分支的直线段。 每个加热器元件包括相对于其上加热器元件和芯突出的水平投影平面部分地与相邻输出线的直线部分重叠的主条带,并且还包括偏转板条,该偏转条从主条带沿着 节点。 每个偏转器条以与节点间隔开的关系延伸,并且与非相关联的输出线的直线段相对于水平投影平面的延伸线大致平行。 偏转器条用于加热通向非活动输出线的节点的一部分,但是为了保持另一部分导致有源输出线不受热不受影响,从而通过节点偏转光,以将其成功地引导到有源输出 线。

    • In an optical attenuator, there are a first optical waveguide 3A connected to an input optical waveguide 1, a second optical waveguide 3B connected to an output optical waveguide 2 and a connecting optical waveguide 4, which are connected with each other in series. A first recess 13A and a second recess 13B are formed in a positional relationship of opposite directions with respect to an axial direction of an optic axis of light that is inputted through the input optical waveguide 1, transmitted through the first optical waveguide 3A, the connecting optical waveguide 4 and the second optical waveguide 3B and outputted from the output optical waveguide 2. Further, a first optical attenuating heater 6A and a second optical attenuating heater 6B are arranged so as to produce opposite refractive index distributions in the axial direction of the optic axis of the light that is inputted through the input optical waveguide 1, transmitted through the first optical waveguide 3A, the connecting optical waveguide 4 and the second optical waveguide 3B and outputted from the output optical waveguide 2, in the first optical waveguide 3A and the second optical waveguide 3B. The optical attenuator capable of reducing a polarization dependent loss for a desired optical attenuation is provided without utilizing an interference of lights.
