We propose a novel square lattice PCF structure featuring a minimum anomalous  group velocity dispersion (GVD), nearly zero third-order dispersion (TOD) and enhanced nonlinearity for efficient soliton–effect compression of femtosecond optical pulses and  supercontinuum generation(SCG) with lowest  input  pulse energies over discrete distances of the fiber. %U https://jce.shahed.ac.ir/article_336_10d0c36a84117e9bbedff9bae496a67c.pdf
