Abstract
An apparatus and method of building multiple-port optical devices characterizes optical filters according to a desired angle of incidence. Fiber ferrules are manufactured to precisely position at least two pairs of optical fibers inside the ferrules. The fiber ferrules are then characterized according to the distance between the fiber cores of the fiber pairs (i.e. the separation distance). The filters and the fiber ferrules are matched according to predetermined tolerances. The filter, or other optical element, is optically aligned with each pair of optical fibers and bonded into place. Light signals, such as DWDM signals, are then transmitted through the devices and the single filter or optical device operates on the multiple signals.
