Comparative Analyses of Multi-Wavelength Converters Based on Electro Absorption Modulators at Various Data Rates

The performance analysis of an electro absorption modulator based multi-wavelength converter that uses a radio frequency generator has been investigated at various input powers (ranging from -3 dBm to 10 dBm) and at various data rates (5 Gbps, 10 Gbps, and 20 Gbps). This was done in order to eliminate the need for an additional pump signal by utilising the RZ (Return to Zero) modulation format. This was done in order to make the solution a more cost-effective one. In this article, a comprehensive investigation of the trade-off between diverse power and varied data rate has been carried out. The input power and data rate are the two most essential operational parameters for wavelength conversion. Because of this, the effect of input power and data rate on the performance of wavelength conversion is investigated in great depth by monitoring the timing diagrams of the signal that has been wavelength converted.
