Refractive index contrast, Δ, is given by Δ = (''n''12- ''n''22)/(2''n''12), where ''n''1 is the maximum refractive index in the core and ''n''2 is the refractive index of the homogeneous cladding. Normal optical fibers have very low refractive index contrast(Δ<<1)hence are weakly guided medium. The weak guiding will cause more of the Electrical field to "leak" and travel through the cladding(as evanescent waves) as compared to the strongly guided waveguides. ==References== * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Refractive index contrast」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
