Propagation mechanism of polymer optical fiber fuse
A fiber fuse phenomenon in polymer optical fibers (POFs) has recently been observed, and its unique properties such as slow propagation, low threshold power density, and the formation of a black oscillatory damage curve, have been reported. However, its characterization is still insufficient to well understand the mechanism and to avoid the destruction of POFs. Here, we present detailed experim...
متن کاملModes and Threshold Power of Fiber Fuse Propagation
あらまし 通信用光ファイバ(SMF 及び NZ-DSF)におけるファイバフューズの伝搬速度と損傷形状の供給 光強度依存性に基づき,その伝搬モードを次の 3 種類に分類した.供給光強度が小さくなる順に,コア領域に閉 じ込められたプラズマがファイバ軸方向に長く広がって伝搬する円筒状モード,その広がりが前者より狭い単峰 状モード,及び半径方向の広がりが前二者よりも小さい不安定モードである.ファイバフューズの損傷形状とし てよく知られた弾丸形状の周期的空孔列は円筒状モードで現れ,単峰状モードでは空孔列が不連続につながり あった線状の損傷が残される.これらの伝搬モードでは,プラズマは半径方向に最大限広がった状態で伝搬する のに対し,不安定モードではそれより狭い領域を伝搬するので,供給光がプラズマに吸収されない比率が大きく, 導波路構造の乱れの影響を受けやすい. キーワード 光ファイバ,ファイバ...
متن کاملFiber Fuse Propagation and Its Suppression in Hole-Assisted Fibers
We examined the characteristics of fiber fuse propagation in hole-assisted fibers (HAF). The fiber fuse propagated in the same way as in conventional single-mode fiber (SMF) when the diameter of an inscribed circle linking the air holes (c) was much larger than the diameter of the melted area (Dmelted). The melted area is caused by fiber fuse propagation and Dmelted is assumed to be almost the ...
متن کاملWave Propagation and Fundamental Solution of Initially Stressed Thermoelastic Diffusion with Voids
The present article deals with the study of propagation of plane waves in isotropic generalized thermoelastic diffusion with voids under initial stress. It is found that, for two dimensional model of isotropic generalized thermoelastic diffusion with voids under initial stress, there exists four coupled waves namely, P wave, Mass Diffusion (MD) wave, thermal (T) wave and Volume Fraction (VF) wa...
متن کاملNeutrino mass matrices leaving no trace
We point attention to the fact that in SO(10) models with non–canonical (type II) see–saw mechanism and exact b − τ unification the trace of the neutrino mass matrix is very small, in fact practically zero. This has the advantage of being a basis independent feature. Taking a vanishing trace as input, immediate phenomenological consequences for the values of the neutrino masses, the CP phases o...
