A STUDY ON IMPACT OF INTENSITY DEPENDENT DISPERSION PARAMETER ON THE PICO SECOND PULSE EVOLUTION IN AN OPTICAL FIBER
AbstractAbstract- In modern optical fiber communication systems, dispersion is a very important factor that decreases the communication quality, especially in Group Velocity Dispersion (GVD) and Third Order Dispersion (TOD). This paper presents a comprehensive study on the pulse distortion due to TOD in an optical fiber. TOD causes broadening as well as pulse breaking effects. Using computer simulation, we examine the effect of intensity dependent dispersion parameter on pico second pulses of various pulse widths. Semiconductor Bloch equations are used to determine the Polarization induced in the medium due to incident Gaussian pulse. The analysis of induced polarization is made by Non linear Schrodinger equation. To represent the pulse propagation behavior linear partial differential equation is used. Our results indicate that intensity dependent TOD effects become more prominent for higher intensities and for short pulse width. Keywords: Group velocity dispersion, pico second pulse, pulse broadening, optical pulse propagation, third order susceptibility, intensity dependent refractive index, Kerr non linearity.
