Multiple port, fiber optic coupling device |
摘要 |
A coupling device has a first focusing element positioned on a first optical axis. The first focusing element is couplable to receive output light beams from a plurality of optical fibers, and has a first focusing power selected to direct the light beams to intersect the first optical axis at a first intersection position. A second focusing element is spaced apart from the first focusing element by a first separation distance along the first optical axis and is positioned to receive the light beams from the first focusing element. The second focusing element has a second focusing power and the first separation distance is selected to parallelize the light beams received from the first focusing element. A system for providing access to light beams propagating through a plurality of fibers uses two of the coupling devices. The two devices are relatively oriented to have opposing second focusing elements so that a beam path of at least one of the parallellized beams from the first device lies coincident and antiparallel to a beam path of at least one of the parallelized beams from the second device. |
