Abstract: 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.
