Abstract
Reshaping an optical pulse into a particular shape has drawn remarkable research interest in last two decades due to their potential applications in the fields of signal processing, ultrafast nonlinear and quantum optics, high power lasers, ultra-high speed optical system etc. Here we present the reshaping of a Gaussian pulse into triangular shape when it propagates through a highly nonlinear normally dispersive chalcogenide fiber (HNNDCF), which has also been designed and optimized by us. Using this chalcogenide fiber one can achieve triangular pulses (TP) having greater stability maintained over a longer fiber length when compared to similar cases in normal dispersion silica fibers.
