Abstract :
A novel way to design tapered nonlinear refractive indices capable to compensate the deterioration of second order bright spatial solitons in a medium with two-photon absorption (TPA), is presented in detail. At first it is shown the effect of TPA over such solitons and then, using a step-by-step adaptive algorithm, we computed the corresponding nonlinear refractive index variation able to keep the beam´s shape and its confinement. This process has proved to be effective and the adaptive algorithm proposed here could certainly be useful for other applications in photonics.
