Tapered optical fiber
Fiberguide Industries
Tapered optical fibers can be made either by fusing a short tapered section onto a longer fixed diameter fiber, or, by very carefully controlling the drawing process to produce a single continuous fiber with an integral tapered section. Fiberguide used the latter process since it results in superior fiber strength, alignment precision and optical power transmission. Tapered optical fibers cause optical mode mixing that tends to homogenize spatial power distribution. A larger input core diameter can prevent input damage and allow a smaller diameter pigtail for convenience in adapting to a wide range of optical applications.
