Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 80, Iss 814, Pp TRANS0141-TRANS0141 (2014)

In this paper, a prediction method of the maximum principal strain of a core/shielding wire contained in a coaxial cable, which is related to the life-cycle of the wire, is proposed. If the central axis of a wire is assumed to be twisted around a vir

Multi-Channel Single-Mode Polymer Waveguide Fabricated Using the Mosquito Method

Autor: Sho Yakabe, Ken Manabe, Hitomi Matsui, Takaaki Ishigure, Yui Kobayashi, Yuki Saito

Publikováno v: Journal of Lightwave Technology. 39:547-556

We experimentally demonstrate that the Mosquito method is capable of fabricating polymer optical waveguides with single-mode cores. The Mosquito method we developed is a technique to form planar polymer waveguides using a commercially available micro

Publikováno v: OFC

We demonstrated a single-fiber multi-core fiber (MCF) connector without additional or high-precision parts for rotational alignment. Fabricated MCF connectors achieved low insertion loss of 0.07 dB in average and passed Telcordia GR-326-CORE mechanic

Low loss single-mode polymer optical waveguide with circular cores

Autor: Hitomi Matsui, Sho Yakabe, Yuki Saito, Ken Manabe, Takaaki Ishigure, Yui Kobayashi

Publikováno v: OSA Continuum. 4:1070

We experimentally demonstrate that the Mosquito method is capable of fabricating single-mode polymer optical waveguides with multiple cores while maintaining an identical mode-field diameter among them. The Mosquito method we developed is a technique

Simple-structure low-loss multi-core fiber LC connector using an align-by-contact method

Autor: Ken Manabe, Tetsu Morishima, Tetsuya Hayashi, Tomomi Sano, Shuhei Toyokawa, Tetsuya Nakanishi

Publikováno v: Optics Express. 29:9157

We present a novel single-MCF connector without any additional or high-precision parts not found on a standard single-SMF connector. The proposed connector realizes rotational fiber alignment and ferrule floating simultaneously by employing a standar

Physical-contact 256-core MPO Connector with Flat Polished Multi-core Fibers

Autor: Tetsuya Hayashi, Tetsu Morishima, Ken Manabe, Tetsuya Nakanishi, Tomomi Sano, Yuki Saito

Publikováno v: OFC

Physical contact of all the cores of ultra-high-density 256-core MPO connectors with 32 strands of 8-core fibers was achieved with a 22-N mating force by polishing method realizing flat fiber facets and small fiber-protrusion difference.

Publikováno v: Japanese Journal of Applied Physics. 45:1913-1916

In situ scanning tunneling microscopy (STM) with highly brilliant hard X-ray irradiation was enabled at SPring-8. To obtain a good signal-to-noise ratio for elemental analysis, an X-ray beam with a limited size of 10 µm was aligned to a specially de
