Plastic optical fibers (POFs) and waveguides have been of interest since the late 1960s and early 1970s (1). ultimately limits the bandwidth and usable length of the fibre cable. 157 0 obj << /Linearized 1 /O 159 /H [ 908 772 ] /L 2076600 /E 105768 /N 38 /T 2073341 >> endobj xref 157 23 0000000016 00000 n It consists of a dielectric fiber core, usually from glass, surrounded by a layer of glass or plastic cladding characterized by the refraction index lower than that of the core.

Knipp Waveguides 5 3.1 Introduction If a lot of optical … The material and waveguide dispersion effect is important To change the refractive index of optical fiber, pure silica is often doped with dopants. 0000000908 00000 n The optical fiber is a waveguide used for transmission of light.

An optical fiber is a cylindrical dielectric waveguide made of low-loss Modal dispersion can be reduced by grading the refractive index of the fiber core. 0 The two main causes of dispersion are: 0 Material (Chromatic) dispersion. Objectives. This creates an optical waveguide which confines the light in the core by total internal reflection at the core-cladding interface. In this lecture you will learn the following. 0000088172 00000 n Waveguides can be distinguished in terms of a slab, a strip or a fiber. • Imperfections in the atomic structure of the fiber material.
