We studied the efficiency of different implementations of the split-step Fourier method for
solving the nonlinear Schrödinger equation that employ different step-size selection criteria …

An efficient algorithm, which exhibits a fourth-order global accuracy, for the numerical
solution of the normal and generalized nonlinear Schrödinger equations is presented. It has …

Variable coefficients nonlinear evolution equations offer us with more real aspects in the
inhomogeneities of media and nonuniformities of boundaries than their counter constant …

Equalization enhanced phase noise (EEPN) occurs due to the interplay between laser
phase noise and electronic dispersion compensation (EDC) module. It degrades …

Optimizing modulation and detection strategies for a given channel is critical to maximizing
the throughput of a communication system. Such an optimization can be easily carried out …

The use of an adaptive step size selection significantly reduces the computational effort for
the numerical solution of the generalized nonlinear SchrOumldinger equation (GNLSE). The …
