- Abstract
We present the results of tan-h pulse propagation through single mode fiber in dispersion dominant regime as well as in the simultaneous presence of fiber loss, group velocity dispersion and self-phase modulation. Both un-chirped/chirped cases have been considered. The pulse was propagated using split-step Fourier method based nonlinear Schrödinger equation. Results clearly show that in the absence of fiber nonlinearity, the pulse goes on broadening with the propagated distance. However, in the presence of the fiber nonlinearity, the pulse initially experiences compression and then undergoes broadening at a faster rate. As the value of sharpness parameter increases, the compression also increases. The results of compensation of group velocity dispersion using dispersion compensating fiber considering the setups of pre-, post- and the combination of pre- and post-compensations are also presented. These investigations provide a detailed study and deeper insight about how fiber responses to such type of optical pulses.
