We consider an optical pulse propagating in a tapered photonic crystal fiber (PCF) wherein dispersion as well as nonlinearity varies along the propagation direction. The generalized nonlinear Schrödinger equation aptly models the pulse propagation in such a PCF. The design of the tapered PCF is based on the analytical results. which demand that the dispersion decrease exponent... https://www.diegojavierfares.com/flash-find-Bushranger-Awning-2-5m-W-x-2-0m-L-2-Year-No-Fuss-Warranty-AW2000-best-save/
