Abstract :
By exploiting the reflection symmetry of the underlying evolution equations, we theoretically demonstrate that stimulated Raman scattering crosstalk in continuous-wave wavelength-division-multiplexed systems can be totally eliminated using spectral inversion techniques. We show that this result is always true, irrespective of the shape of the Raman gain curve or the loss/gain profile along the optical fiber system. These results are illustrated by means of relevant examples.
