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://parisnaturalfoodes.shop/product-category/deodorant-spray-unscented/
