“…The QCT method adopted in this paper is similar to that described in the previous literatures. [23][24][25][26][27][28] In our QCT calculations, the classical Hamilton equations are integrated numerically in three dimensions. Meanwhile, for each trajectory, the numerical integration accuracy is verified by checking the conservations of the total energy and the total angular momentum.…”

A quasi-classical trajectory (QCT) calculation is used to investigate the vector and scalar properties of the D + BrO → DBr + O reaction based on an ab initio potential energy surface (X1A’ state) with collision energy ranging from 0.1 kcal/mol to 6 kcal/mol. The reaction probability, the cross section, and the rate constant are studied. The probability and the cross section show decreasing behaviors as the collision energy increases. The distribution of the rate constant indicates that the reaction favorably occurs in a relatively low-temperature region (T<100 K). Meanwhile, three product angular distributions P(θr), P(ϕr), and P(θr, ϕr) are presented, which reflect the positive effect on the rotational angular momentum j’ polarization of the DBr product molecule. In addition, two of the polarization-dependent generalized differential cross sections (PDDCSs), PDDCS00 and PDDCS20, are computed as well. Our results demonstrate that both vector and scalar properties have strong energy dependence.

“…Joint compensation of dispersion and nonlinearity has been proposed within 084203-3 the regime of optical orthogonal frequency division multiplexing. [13] For the PM systems, it has also been demonstrated that the nonlinear impairments as well as the dispersion can be efficiently compensated for simultaneously by OPC-based nonlinearity compensation techniques, [14,15] and mid-nonlinearity temporal inversion (MNTI) offers the best performance almost independently of the system characteristics. [8] Another advantage of OPC-based compensation methods lies in their good performance in real time and their transparency to the modulation format.…”

The Gordon—Mollenauer Effect in 112 Gbit/s DP-QPSK Systems

Gordon and Mollenauer (G-M) proposed in 1990 that the interplay between the nonlinear Kerr effect and amplified spontaneous emission noise can generate an enhanced level of noise and degrade the performance of optical phase-modulated systems. We systematically investigate the G-M effect in 112 Gbit/s coherent dual polarization quaternary phase shift keying (DP-QPSK) systems through comprehensive simulation. The results show that in the presence or absence of inline dispersion compensation, the G-M effect will seriously damage the system performance. Some of our important conclusions are listed as follows: with the increase in the input power into each span, the G-M effect is enhanced simultaneously; the smaller the span length, the stronger the G-M effect caused by more inter-span interaction; for non-zero dispersion-shifted fibers, different coefficient values will cause a similar amount of G-M effect penalty; by comparing the system performance with different dispersion compensation ratios, one can conclude that different residual dispersions of the same magnitude, no matter whether they are under-compensated or over-compensated, can derogate the overall system performance to a similar degree. In brief, the G-M effect cannot be ignored. We also have a short discussion on how to reduce and compensate for the G-M effect in DP-QPSK systems.
