Abstract:
1. A dispersion slope compensator for compensating for dispersion slope which optical signals undergo, comprising: a substrate; a movable optical component disposed opposite to a side of the substrate to provide an optical path that guides a light emanating from one point on the side of the substrate to another point on the same, the movable optical component being movable in a perpendicular direction with respect to said side of the substrate; a looped optical line comprising an optical waveguide fabricated on the substrate; a variable-length input-and-output optical line formed from the optical path of the movable optical component and two optical waveguides fabricated on the substrate; and two optical couplers fabricated on the substrate to couple the looped optical line to the variable-length input-and-output optical line at two points.
