| dc.description.abstract | Study of non-linearity in optical ber material has attracted tremendous attention over last two decades. Despite many experimental and theoretical e orts to nd the origin of non-linearity and to quantify the loss due to non-linearity still a debable issue. The aim of this project work is to nd a mechanism and to quantify non-linearity that causes attenuation and dispersion in optical ber. We speci - cally calculated solution to non-linear envelope equation (non-linear Schr odinger equation ) from Maxwell is theory choosing appropriate envelope function. Our calculation are in agreement with other researchers as far as loss and non-linearity are con cerned. We found the Soliton solution which is very interesting result that can be further looked at in detail to observe the non-linear e ect in ber material. It is found that the non linearity balances dispersion and a stable pulse is formed which does not alter its shape during propagation. This simple calculation gives understanding for the mechanism of the origin of non-linearity. Moreover, it helps to control non-linearity by tuning some of the componsion of ber material | en_US |
