Abstract
An optical connector system comprises mating first and second fiber ferrules (1, 11). Each ferrule (1, 11) has an endface (4, 14) polished at an angle to minimize backreflections. A holographic optical element (6) disposed on the first ferrule endface (4) receives a transmitted beam and expands the beam to an expanded beam (21) of collimated light. The expanded beam (21) is launched into an air gap (22) for receipt by a holographic optical element (16) disposed on the second ferrule (11). The holographic optical element (16) on the second ferrule (11) receives the expanded beam (21) and focuses it to be received by the fiber held in the second ferrule (11).
