摘要

通过去除弯曲单模光纤外部的包层并以小于辐射焦散的半径暴露表面，可以抑制传播模式的泄漏性质并消除弯曲损耗。本文描述了这种效应的实际实现，并证明了在标准电信光纤上弯曲半径为0.50 mm而损耗可以忽略不计。

Removing bend loss by removing the caustic in bent single mode fibres

By removing the cladding on the outside of a bent single mode optical fibre and exposing a surface at a radius smaller than that of the radiation caustic, the leaky nature of the propagating mode is suppressed and bend loss is eliminated. In this paper the practical realisation of this effect is described, and a bend radius of 0.50 mm on standard telecommunications fibre is demonstrated with negligible loss.
