  • Fiber-to-fiber coupling using interference to minimize power loss
    Patent number: 6883972
    Abstract: An optical fiber coupling reduces power loss by creating breaks in one or both of the optical fibers being joined so that destructive interference between modes of the signal escaping at the coupling and the breaks reduces total power loss. The breaks can be in the receiving and/or transmitting optical fiber, and each break generally correspond to a small region of changed refractive index in the cladding and/or core of an optical fiber. The breaks can be created using a laser or by removal and replacement of small regions of cladding material. An active alignment process can position the optical fibers for physical attachment.
