“…For this purpose, the direct connection using 3D waveguide is considered in this paper and one of the issues is misalignment. 13) Misalignment between MCF and 3D waveguide and/or 3D waveguide and optical mode switch occurs. As an example, take the following case: between two singlemode fibers which have a 6 μm core.…”

3D waveguide is attractive because it has a potential that the waveguides are arranged, not only in plane, into three-dimension. Mosquito method, of which the core and cladding material sources are liquid and will be cured using UV-light, is known as one of the ways to fabricate the 3D waveguide. In this method, if multiple waveguides are fabricated, time until UV-cure is different between first waveguide and last one and it leads to core position shift because of gravity. To solve the problem, we considered to reduce the time from the first waveguide formation to the UV-cure using automatic waveguide fabrication with a camera. For the automatic waveguide fabrication, YOLO (you look only once) and OpenCV is exploited as machine-learning and image-processor, respectively. As a result, waveguide recognition time of 10 ms and image processing time of 50 ms, totally 60 ms, are realized.

“…Optical loss in a fiber connection has four causes: fiber-core offset, fiber-axis tilt, fiber-end separation, and mode field mismatch [17,18]. With MT connectors, fiber-core offset is the dominant factor generating optical loss, and so we have limited our considerations to this factor.…”

This chapter reports the latest mechanically transferable (MT) and multifiber push-on (MPO) multifiber connector technologies. Low insertion-loss and high return-loss angled physical contact (APC)-MPO single-mode multifiber connectors are developed. For these multifiber connectors to achieve a high performance, it is necessary to reduce deviations of all components and to control fiber offset due to shear force caused by compressing two obliquely ended MT ferrules. MT single-mode 84-fiber connectors are developed to realize higher density multifiber connectors. We have developed a novel high-density optical cable joint that has a 24-connector array consisting of new 84-fiber MT connectors. The new cable joining technique significantly shortens the time needed to join the optical fiber cables. Novel optical fiber switches are developed on the basis of MT multifiber connector technology. The switches use a manual guide-pin slide method in special guide holes in a novel multifiber array. Because high precision multifiber connectors need to be measured and inspected, a new inspection technique for MT ferrules is developed and equipment for it is fabricated. The fabricated inspection equipment can measure MT ferrules with high speed, cost effectiveness, and high accuracy. These single-mode multifiber connectors can be used as key technologies for advanced optical fiber communication systems.
