Abstract
We demonstrate that all the inter- and intra-channel nonlinear impairments can be eliminated simultaneously by optical phase conjugation (OPC) in a power-symmetry system. However, for practical systems without power-symmetry, it is found that the effects of OPC on various nonlinearities are different in the same link. Even some nonlinearities are suppressed and some are enhanced. Therefore, optimizing the transmission link with OPC to suppress the dominant nonlinearity is demanded. By using 1-km-long highly nonlinear fiber (HNLF) and tuning the pump wavelength near the zero dispersion wavelength of the HNLF, we experimentally generate the phase conjugation of the dispersed ~300 fs pulses. OPC with conversion efficiency of about -16 dB and conversion bandwidth of about 38 nm is obtained.
