MULTICORE OPTICAL FIBER FAN-IN/FAN-OUT DEVICE

Abstract: a fan-in/fan-out device and method for fabrication thereof. the device includes a tapered assembly having a narrow end with an end face and a wide end from which a plurality of composite core optical fibers extend. each composite core optical fiber includes a cladding and a composite core having first and second cores. the cladding and cores all have different indexes of refraction. the tapered assembly end face includes a fused cladding region comprising the claddings of the composite core optical fibers and the composite cores thereof. the composite cores are arranged in the fused cladding region to define a core pattern that matches the core pattern of a multicore optical fiber. the tapered assembly is fabricated by inserting the composite core optical fibers into a silica tube, heating the tube and fiber assembly to a softening temperature, and pulling apart the ends thereof.
