Dispersion Modelling of Micro Structured Optical Fibres for Telecommunications Deployment | Original Article

ABSTRACT:

Chromatic dispersion is a critical issue in the design of optical fibers due to pulse spreading. It is related to the variation in group velocity of optical signals in a fiber. The term “chromatic” emphasizes its wavelength dependent nature. Chromatic dispersion limits the maximum distance, to which a pulse can be transmitted without the necessity of regeneration of its shape, timing, and amplitude. Pulse broadening can deteriorate performance of a high bit rate systems. Hence it is essential to either prevent the occurrence of dispersion or provide adequate compensation for it. In this regard Micro structured optical fibers [MOFs] or Photonic Crystal Fibers (PCF) or Holy Fibers [HFs] display tailor able unique dispersion properties in comparison to conventional silica optical fibers. This paper presents a systematic study of dispersion properties of PCFs along with its dependence on structure and material used. An overview of current innovations on this issue also is mentioned.
