Optimum Hollow Core Fiber Design for Long Haul Optical Communication System

Abstract

Photonic Crystal Fibers (PCF) are gaining great importance now a days in the field of photonics and optical communication due to their wide range of nonlinear applications with reduced fiber losses. It is an alternative fiber technology with improved optical properties due to light confinement within the air holes of its cladding along with the light propagation through the core. In this research we have designed, optimized and then analyzed light through hollow core PCF to obtain its characteristics. Different optical properties such as waveguide dispersion, confinement loss, attenuation and signal to noise ratio is investigated. Low attenuation of signal is reported as the length of fiber is increased. Purpose of this research is to present a design of HC-PCF that can be used in long haul optical communication where low but a non- zero chromatic dispersion is required for a low attenuation as we move along the fiber. Non-linearity in the signal causes attenuation which in case of PCF can be minimized to reduce the signal attenuation. Signal to Noise ratio is automatically improved when the signal is not getting attenuated along the length of the fiber. Main purpose of this research was to introduce a new structure and design of latest field of microstructured fiber technology instead of conventional optical fiber technology. We have investigated our design of HC-PCF for telecommunication application over range of wavelength from 1000nm to 1650nm.
