Photonic crystal-based strain visualization film is promising for detecting the age-related deterioration of large man-made structures an...

Several nano liters of tellurite glass melt (xTeO2 - (100 - x)ZnO, x = 80,90,100 in mol%) were inserted and quenched between tow ends of ...

1988年以降のファイバヒューズの伝搬に関する知見を簡単にまとめた。この奇妙 な現象は、巨視的に見れば、散逸ソリトンという概念と野火との類似性に着目す ることで容易に理解できる。熱で誘起されたシリカガラスの強い光吸収と、レー ザーエネルギーの極度に集中した供給が、閉じ込めら...

Knowledge accumulated about fiber fuse propagation since 1988 is briefly summarized. From a macroscopic viewpoint, the dissipative solit...

白色タイトバッファ付き単一モード光ファイバにおけるファイバフューズ伝搬しきい値が、透明なアクリル樹脂被覆ファイバにおける値よりも3%小さいことが分かった。これは、バッファー層の白色顔料が可視光発光を後方に散乱させてファイバフューズを光励起するためである。すなわち、移動するプ...

2008年11月に運用が始まった、NIMS eSciDocシステムの研究者ユーザとして、研究成果の発信に活用した例を紹介する。学術論文の著者最終稿であっても、それを公開する意味は大きく、ダウンロード数データは雑誌の購読契約を結んでいない読者層(専門外の読者や文系研究者)の存...

My outreach activities based on NIMS eSciDoc system (PubMan \& Imeji) since Nov. 2008 is presented. Top two downloads during the past th...

The results of my simple efforts to start my presentation with a short greeting in the audience's language.

Since I have been publishing my research papers mainly in open access journals, most of my self-archived articles, including English tran...

Researchers dislike miscellaneous affairs. Because they cannot devote themselves to their study. Then, do you think that self-archiving...

A short essay for non-science oriented readers describing author's serendipitous research on optical fibers and the lessens learnt.

Ultrahigh-speed photographs of fiber-fuse propagation in single-mode silica fibers revealed a new factor, other than pumping laser power ...

Several nano liters of tellurite glass melt was inserted and quenched between two ends of silica glass optical fibers to form a optical ...

Critical cooling rate Q for zinc tellurite glass system is determined based on the time-temperature-transfer (T-T-T) diagrams, wh...

Less than 1.5dB of insertion loss was realized in an optical coupling structure in which two TEC (Thermal-diffusion Expanded Core) fibers...

Combinatorial methods bring about enormous data not only in size but also in dimension. To handle multi-dimensional data easily, a conce...

Excessive-light-induced melt down was observed in a carbon-coated TeO2 glass segment formed between a pair of optical fiber end-faces. T...

Fluorescence lifetime of Er3+ was measured for F-doped tellurite glasses with parallel heat treatment under a temperature gradient atmosp...
