All Optical Multi-Wavelength Conversion and Data Format Conversion Based on Dual-Pumped Fiber Optical Parametric Amplifier
By the combination of data intensity modulated pump and continuous wave pump or sinusoidal intensity modulated pump, all optical multi-wavelength conversion and multi-wavelength conversion with data format conversion are presented by using a dual-pumped fiber optical parametric amplifier (FOPA). The operation principle is analyzed with respect to the gain. Experimentally, the multi-wavelength conversion and multi-wavelength conversion with data format conversion between non-return-to-zero (NRZ) and return-to-zero (RZ) are demonstrated under the bit rate of 2.5Gb/s. The experimental results indicate that the dual-pumped fiber optical parametric amplifier is able to implement multi-wavelength conversion to achieve normal and invert pattern with some degree of regeneration. The data format conversion gives the signal with duty ratio of 30% and improved extinction ratio.
