Abstract

We studied numerically and experimentally an ultrafast passive nonlinear temporal reshaping mechanism based on spatial soliton emission in Ti periodically poled lithium niobate waveguides combined with spatial filtering. We demonstrated efficient temporal reshaping of 4-ps pulses at 1548 nm.
