Abstract
Efficient coupling between multimode optical fibers and optical devices, such as optical detectors and light emitting diodes, is realized by means of a coupling arrangement comprising a length of homogeneous glass fiber, terminated by a convex microlens. One end of the glass, whose length is greater than the focal length of the microlens, is fusion-spliced to the multimode fiber. The convex microlens is formed at the other end of the homogeneous glass member.
