    • In an example embodiment, lightwave device for use in a dispersion compensator, includes a light coupler configured to direct light toward a grating structure. The light coupler includes a first strip including a first material and a second strip attached to the first strip. The second strip includes a second material, and the second material has an expansion coefficient different than the first material. The first and second strips form a deformable reflector. A thermoelectric unit is coupled to the light coupler and is configured to adjust a shape of the deformable reflector based on a temperature of the thermoelectric unit. A support member is connected to the light coupler and is configured to position the deformable reflector so to receive light for transmission to the grating structure. Another embodiment provides a dispersion compensator using the lightwave device.
    • 在示例实施例中,用于色散补偿器的光波器件包括被配置为将光引向光栅结构的光耦合器。 光耦合器包括包括第一材料的第一条带和附接到第一条带的第二条带。 第二条带包括第二材料,第二材料具有不同于第一材料的膨胀系数。 第一和第二条带形成可变形的反射器。 热电单元耦合到光耦合器并且被配置为基于热电单元的温度来调节可变形反射器的形状。 支撑构件连接到光耦合器并且被配置为将可变形反射器定位成接收光以传输到光栅结构。 另一实施例提供使用光波器件的色散补偿器。
