Abstract
An optical interconnect system (100) includes an array of optical sources (102), a high-density fiber bundle (110), and an array of optical receivers (150). The density of the fiber bundle is such that each optical source (104) couples light to multiple fibers within the bundle. The fiber bundle has a consistent cross section along its length so that the footprint of fibers (306, FIG. 3) illuminated by a spot (304) from an optical source illuminates a similar footprint (404, FIG. 4) over the optical receivers (406). The optical receiver array has a density of optical receivers such that the footprint of fibers corresponding to a single optical source illuminates at least one optical receiver. A method (600, FIG. 6) for creating optical source/receiver pairs excites each optical source in turn and detects energy at the optical receiver array.
