This lesson demonstrates the energy exchange between two optical solitons with orthogonal polarizations associated with the orthogonal Raman gain .
Using equations (17a) from the technical description of the Nonlinear dispersive fiber component it can be shown  that the energy exchange between two solitons:
where P1 > > P2 and Δ ω > 0 is approximately given by the following expression :
Equation 2 denotes the energy of the weaker (low frequency) soliton.
The layout and its global parameters are shown in Figure 1.
