Abstract

　コアとコアの外周に形成したクラッドとを備え、半径方向における屈折率分布をｎ（ｒ）、コア中心における屈折率をｎ１、コア中心のクラッドに対する比屈折率差をΔ１、コアの半径をａ、屈折率分布パラメータをα、「＾」をべき乗を示す記号とすると、ｎ（ｒ）は０＜ｒ≦ａにおいてはｎ（ｒ）＝ｎ１[１－２（Δ１／１００）(ｒ／ａ)＾α]１／２、ａ＜ｒにおいてはｎ（ｒ）＝ｎ１[１－２（Δ１／１００）]１／２で近似され、αは１．９５～２．１５、比屈折率差は１．５％以上、コアの直径は２０～４５μm、クラッドの直径は７０～９０μm、曲率半径５ｍｍで曲げたときの波長８５０ｎｍにおける曲げ損失が０．１ｄＢ／ターン以下である。これによって、高速光伝送が可能であって、曲げ損失が小さく、低コストかつ容易に製造できる光ファイバおよび光ファイバテープならびに省スペースで低コストの光インターコネクションシステムを提供する。
