先んずれば人を制す、写真撮らばファイバフューズ
Description/Abstract:
世界で初めて「ファイバフューズ伝搬のその場観察」を成功させるまでの経緯をエッセイ風にまとめた。廊下の研究発表ポスターを見て売り込みに来た営業マンを通じて、超高速度カメラのデモ撮影を行ない、偶然が重なって手にした結果を国際会議に発表申込したところ採択された。その舞台裏には、ラ...

光ファイバの"路芯"溶融伝播―ファイバフューズ現象とその対策
Description/Abstract:
高強度光源の普及により顕在化してきた問題であるファイバフューズについて解説する。数Wの光を伝搬している光ファイバを折り曲げるなどして局所的に加熱すると、コア領域にブラズマが生成し、光ファイバ内に閉じ込められつつコア領域を破壊しながら光源方向に移動する現象が発生する。発生する...

ファイバフューズ―その危うさと怪しさ
Description/Abstract:
光ファイバが長距離に渡って破壊される現象であるファイバフューズに関して、現在までに分っていることをまとめたのち、筆者の研究を紹介する。毎秒約1mで動くファイバフューズを超高速カメラで撮影し、また残された損傷の光学顕微鏡映像を統計処理することで、損傷発生のメカニズムについて推...

ファイバフューズの自然停止に伴う2重周期的空孔列の生成
Description/Abstract:
シリカガラス製単一モード光ファイバにファイバフューズを発生させた後、供給エネルギーを減少させてヒューズを自然停止させたところ、停止位置近傍に生成された空孔列に2重周期的規則性が見出された。自然停止直前の挙動を超高速ビデオカメラで撮影したところ、空孔列が途切れる部分で閃光を発...
