Analysis of light propagation through Photonic Crystal Fiber Design with reduced losses

We are living in the society of information where it is vital to communicate information as quickly and efficiently as possible. In order to improve the efficiency of telecommunication industry, latest technology of fibers has to be studied, analyzed and implemented. The journey of optical fibers to Photonic Crystal Fibers during the last few years is a positive step towards the improvement of communication industry. This research work presents a model for electromagnetic wave propagation through the photonic crystal fiber with the help of a technique known as Finite Difference Time Domain (FDTD). For the efficient and effective propagation of light through this fiber, it is first important to have a PCF design with lowest possible loss and dispersion. In this work, we first analyzed different designs of PCF, compared them with the commercially available designs and then selected the one model with lowest possible loss and dispersion. Light was then passed through that fiber and simulations were done for 25 km long fiber.
