Recent Developments in Optical Fiber Technologies

Optical fibers are transparent fibers which are produced by drawing glass or plastic to a diameter slightly bigger than that of human hair. They are flexible in nature and are used to transmit light. They work on the principle of total internal reflection of light and are immune to electromagnetic interferences. Depending upon the refractive index, optical fibers are classified into step index and graded index fibers. They find extensive applications in the fields of telecommunication, comp...
