Photonic Crystal Fibre: Developments, Properties and Applications in Optical Fiber Communication

Abstract

The increasing demand of demand for internet and high data rate is offered by optical technology but it faces some deficiencies like the flexibility in designing and efficient use of complete optical spectrum. Photonic crystal fibers comes in a new category of optical fiber system that reduces all the drawbacks of the conventional optical fibers. Photonic crystal fiber is fabricated with periodically arranged low index material in a background with high refractive index material. Light can be guided inside the PCF by either modified total internal reflection or photonic band gap guidance. PCFs are widely used in spectroscopy, meteorology, bio-medicine, imaging, telecommunication, industrial machinery etc. This review paper gives an overview on Photonic Crystal Fiber (PCF) & its applications. This paper discusses the importance of photonic crystal fibers,its, guided mechanism, its structural properties and its applications in optical fibre communication.
