Optimization of dispersion-managed optical fiber lines

Influence of laser chirp and parasitics on optimized dispersion-managed directly modulated systems operating at 10 Gbit·s^-1

“…Besides, it has been shown in Ref. [5] that this approach does give indications about the ODM, similar to the ones achieved by taking into account also the amplifier noises, but in a very much efficient simulation time. It should be stressed that using this approach enables an easy comparison between the ODM for DM/DD multi-span systems, with the ODM for the IM/DD multi-span system presented in Ref.…”

“…Several studies of high-speed multi-span conventional intensity-modulated (IM)/DD systems, have been reported. These studies indicate that the introduction of DCF-based dispersion-management technique allows the mitigation of accumulated GVD in multi-span conventional IM/DD transmission systems with high bit rates [4,5].…”

“…Therefore, the stochastic effects, such as the ones due to the laser and amplifiers noises, are neglected. This approach has been extensively used to find the ODM of different transmission systems [4,5]. Besides, it has been shown in Ref.…”

Ground states for the higher-order dispersion managed NLS equation in the absence of average dispersion

“…Due to (18) we can always restrict our attention to 1 , 2 , 3 ∈ supp(û), whence 1 , 2 , 3 * − R * /2 by assumption. Accordingly, by Lemma 2.7(a) below we can estimate for an appropriate 0 > 0,…”

“…A natural extension of this work was to study the variational problem with = 0. This problem, while interesting from an analytical point of view, is also important physically, as certain physical effects that are destabilizing to pulse propagation in an optical fiber are minimized in the regime ≈ 0 [18,20]. Due to Strichartz-type estimates for solutions of linear dispersive equations [7], the corresponding Hamiltonian is bounded from below in L 2 = L 2 (R; C).…”
