GVD and SPM optimization in optical fiber using a hybrid method

Abstract

Ultrashort pulses have broad bandwidth and power, which are useful to TX and RX with optical fiber. When a pulse generator is connected to SMF, dispersion and nonlinear effects can be presented such as GVD and SPM. These phenomena cause problems like decreasing the signal power and acquiring undesired frequency components. To compensate these effects, a hybrid method is proposed by means of optimal control, genetic algorithm and fuzzy clustering techniques, consequently to find the appropriated values of the parameters that allow optimizing the pulse. The results of the simulation displayed a reduction of bandwidth plus an increase in the signal amplitude, and thus both effects were mitigated.
