An optical fiber is a long cylindrical dielectric waveguide, usually of circular cross-section, transparent to light over the. OPTICAL FIBER WAVEGUIDE. Optical Fiber Waveguides. An Optical Fiber is a dielectric waveguide that operates at optical frequencies; Normally cylindrical form; It confines electromagnetic energy in the form of light to within in its surfaces and guides the light in direction parallel to its axis. Optical Fiber Waveguides. core. In this chapter we shall discuss from both a ray and wave standpoint how light can be guided along by planar and cylindrical dielectric waveg- uides. We shall explain why optical fibers are important and useful in optical communication systems and discuss briefly how these fibers are manufactured. Some practical details of An optical fiber is essentially a waveguide for light; It consists of a core and cladding that surrounds the core; The index of refraction of the cladding is less than that of the core, causing rays of light leaving the core to be refracted back into the core; A light-emitting diode (LED) or laser diode (LD) can be used for the source EE 230: Optical Fiber Communication Lecture 3.
