| Research Abstract |
In long-haul large-capacity frequency division multiplexing optical fiber transmission systems, four-wave-mixing (FWM) light is generated due to the third-order nonlinear optical effect. The FWM light is incident upon the receiver with the signal light, and the FWM light is the cause of the noise. In this research, new allocations of light frequencies, signal pulses, and polarizations were proposed and the FWM noise was analyzed. Both FWM noise and the total frequency bandwidth were reduced.
