Abstract

A photonic approach to generate a triangular-shaped pulse utilizing the self-convolution process of a rectangular-shaped pulse is proposed and demonstrated. The configuration is characterized by two sections of dispersive fibers with opposite signs connected by a parametric mixing process, which corresponds to a temporal reduced 4-f system in addition, with a pattern square operation at the Fourier plane. The proposal is analyzed and validated by simulation and experiment, and triangular pulses with different pulse widths are successfully generated.
