Generation of optical super-Gaussian pulses using tapered fibers

Using a model for the shape of tapered fiber optics, we numerically study the effect of the taper shape profile on nonlinear optical pulse propagation. We show that super-Gaussian pulses can be generated and controlled and they are independent of higher-order nonlinearities, which makes them a good candidate for optical communications. We see that it is possible to compensate for the z variation of the dispersion with the nonlinear parameter and obtain the solutions of the homogeneous nonlinear Schroedinger equation.
