square lattice elliptical-core photonic crystal fiber soliton-effect compressor at 1550nm

In this paper, we investigate the evolution of supercontinuum and femtosecond optical pulses generation through square lattice elliptical-core photonic crystal fiber (pcf) at 1550 nm by using both full-vector multipole method (m.p.m) and novel concrete algorithms: symmetric split-step fourier (ssf) and fourth order runge kutta (rk4) which is an accurate method to solve the general nonlinear schrodinger equation (gnlse). 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.
