Abstract

In this work, cross absorption modulation (XAM) or high-speed optical transmission in electroabsorption modulator (EAM) has been utilized to investigate all-optical multi-wavelength converter. 40-Gbps data signal with NRZ format is considered to analyze the impact of various input parameters of EAM. The input power (launched power) of the signal and bias voltage on multi-wavelength conversion is validated in optical signal-to-noise ratio (OSNR), Q factor, and received power. The main highlight of this investigation is to find the optimal operating parameters of EAM for designing the perfect wavelength converter. The range of input power of the signal tuned from 15 to 21 dBm and a bias voltage of EAM tuned from 0 to -3 V are utilized to investigate the Q factor and converted signal power of multi-wavelength converter and found the best possible bias voltage is -2.0 V and input signal power at 15 dBm. The optimal converted signal quality is obtained at 1548 nm and 1550 nm with reverse bias voltage at 1.5 V and 2 V.
