Abstract

In summary, we have investigated the effect of nonlinear intensity filtering. We have developed a phasor model to explain the nonlinear filtering effect. From these results we can derive approximate equations for the design of the intensity filters. Furthermore, we have calculated the points of equal pulse compression which occur in nonlinear pulse propagation in a fiber. Combining the design rules for noise squeezing and equal pulse compression we have proposed a new design for an intensity filter suitable for noise squeezing and pulse reshaping.
