Device for controlling polarization of optical fiber and method of controlling polarization of optical fiber using same

摘要

A device for controlling polarization of an optical fiber and a method of controlling the polarization of an optical fiber using the same are disclosed herein. The device includes optical fiber supports, an optical fiber holder, and an optical fiber curvature changing unit. The optical fiber supports receive an optical fiber, and support both ends of the optical fiber. The optical fiber holder includes an optical fiber guide element that guides the optical fiber, drawn out of the optical fiber supports, through a path. The optical fiber curvature changing unit is located between the optical fiber and the optical fiber guide element, and changes the curvature of the optical fiber by exerting external force onto the optical fiber.

1. A device for controlling polarization of an optical fiber, comprising:
optical fiber supports configured to receive an optical fiber and support both ends of the optical fiber; an optical fiber holder configured to include an optical fiber guide element that guides the optical fiber, drawn out of the optical fiber supports, through a path; and an optical fiber curvature changing unit located between the optical fiber and the optical fiber guide element, and configured to change a curvature of the optical fiber by exerting external force onto the optical fiber in a direction perpendicular to the extension direction of the optical fiber, wherein the optical fiber holder has slots intersecting the path of the optical fiber, and the optical fiber curvature changing unit comprises movable members that are inserted into the slots and are movable along shapes of the slots.
