More Information
Summary:A mode scrambler capable of converting the mode distribution of light transmitted through an optical fiber into a stationary mode distribution. The mode scrambler comprises a plurality of cylinders arranged in a predetermined arrangement, and a step index optical fiber of 100 mu m or above in core diameter and 0.4 or above in numerical aperture wound around and across the plurality of cylinders. The step index optical fiber is wound at least in one 8-shaped wind at least across two cylinders of the plurality of cylinders. At least the diameter of one of the two cylinders across which the step index optical fiber is wound in an 8-shape is not less than ten times and not more than fifty times the core diameter of the step index optical fiber, and the diameter of the other cylinder is not less than that of the former cylinder.
