13.1 Introduction

In the middle of the 1800s, experiments demonstrated that light can travel through a curved stream of water or a curved glass rod by total internal reflection (Daniel Colladon in 1841, Jacques Babinet in 1842, John Tyndall in 1854). However, the first all-glass optical fiber which had a higher index core surrounded by a lower index cladding was realized almost one hundred years later. Kao was the first who identified the critical specifications of the fibers that are needed for low loss long range communication [1–3]. The advent of new manufacturing processes led to the achievement of the theoretical ...
