Abstract :
We investigate the energy coupling among different frequency carriers by partially degenerate four-wave mixing in single-mode fibers. We show that for a multichannel lightwave system operated near the zero-dispersion frequency of the single-mode fiber, four-wave mixing may cause significant signal depletion in a channel whose power acts as a pump in the four-wave mixing process. Analytical solutions are derived and the signal depletion due to four-wave mixing is obtained.<>
