Paper Abstract

When an optical pulse with super-Gaussian shape is transmitted in fiber, it will gradually evolve to Gaussian function shape under suffered all kinds of effects, such as group velocity dispersion (GVD), third order dispersion (TOD), forth order dispersion (FOD), and nonlinear effects. An interesting phenomenon is observed, that is, TOD will transfer energy of super-Gaussian pulse from one half to another within total flat top, but TOD will split Gaussian optical pulse and bring strong oscillation structure in the edge of pulse. Corresponding to frequency domain, super-Gaussian pulse has two evident slide slobs arranged in both sides of main peak, but TOD can make slobs fade away and transform frequency spectral to Gaussian function shape. In a densely dispersion managed (DDM) fiber system, the propagation performance of super Gaussian pulse with sub-picosecond pulse width is investigated. From clear eye-diagram of propagating over 1000 km, we can conclude that the DDM fiber system is very suitable for super Gaussian optical pulse transmission under low system power condition.
