Figure 5From: Exact spatiotemporal soliton solutions to the generalized three-dimensional nonlinear Schrödinger equation in optical fiber communication Density \(\pmb{|u_{3}|^{2}}\) as a function of propagation distance \(\pmb{L\equiv x+y+t}\) and z given by Eq. ( 44 ), with (a) \(\pmb{F(\xi)=\tanh(\xi)}\) , (b) \(\pmb{F(\xi)=\operatorname{sech}(\xi)}\) , (c) \(\pmb{F(\xi)=\mathrm{sn}(\xi)}\) , \(\pmb{M=0.5}\) and (d) \(\pmb{F(\xi )=\mathrm{cn}(\xi)}\) , \(\pmb{M=0.5}\) .
