ENERGY COUPLING BY PARTIALLY DEGENERATE 4-WAVE-MIXING IN MULTICHANNELLIGHTWAVE SYSTEMS

We investigate the energy coupling among different frequency carriers by partially degenerate four-wave mixing in single-mode fibers, We sho w that for a multichannel lightwave system operated near the zero-disp ersion frequency of the single-mode fiber, four-wave mixing may cause significant signal depletion in a channel whose power acts as a pump i n the four-wave mixing process. Analytical solutions are derived and t he signal depletion due to four-wave mixing is obtained.
