Device for the control and adjustment of the modal alignment of optical fibers

摘要

A device for the control and adjustment of the modal alignment of optical fibers is described. The device includes at least one laser (20) delivering an electromagnetic beam, and at least one mode selector (26) suitable for acting on the beam so as to produce a TEM1, j-1 type modal structure, the modal structure having an axis of symmetry (15). Also included in the device are a marker for marking at this axis of symmetry (15) orientation variations around an axis (RR1); an introducer for introducing the electromagnetic beam into an optical fiber (10); and a measurer (36) for measuring luminous power. The device is particularly adapted for the adjustment of the alignment of optical fibers as regards their connection and for centering an optical fiber in a plug connector.
