We investigate the computational cost of the nonlinear Fourier transform (NFT) based on the Zakharov–Shabat scattering problem as a nonlinear compensation technique for quadrature-phase-shift keyed (QPSK) signals with raised cosine frequency charac

The Raman effect causes higher-order solitons to break apart, leading to inter-symbol interference, even in the ideal case without propagation losses. The power threshold of this effect is 10 dBm for a two-eigenvalue QPSK system.

We show that nonlinear transforms based on the Zakharov-Shabat scattering problem are not practical to encode/decode QPSK signals in communication systems with normal dispersion fibers operating with average powers above that of the quasi-linear regi

We introduce a fully deterministic computationally efficient method for characterizing the effect of nonlinearity in optical fiber transmission systems that utilize wavelength division multiplexing and return-to-zero (RZ) modulation. The method is ba

We numerically demonstrate the feasibility of return-to-zero differential phase-shift keying transmission at 80 Gbit/s channel rate using cascaded in-line semiconductor optical amplifiers.

This paper demonstrates a multichannel wavelength conversion of differential phase-shift-keyed (DPSK) signals using four-wave mixing in a highly nonlinear fiber. The wavelengths of three 10-Gb/s nonreturn-to-zero (NRZ) DPSK channels are simultaneousl

A theoretical analysis and an experimental demonstration of semiconductor optical amplifier (SOA)-based regenerative amplification (SORA) of phase noise (PN)-degraded return-to-zero (RZ) differential phase-shift keying (DPSK) signals are presented. T
