Abstract

A novel linearization process in electroabsorption modulated laser (EML) is proposed and experimentally demonstrated. Dual-parallel modulation scheme is used to compensate the nonlinear component of the EML by controlling the DC bias voltages of the each EML separately. The simulations on the nonlinearity of EML and linearization process are performed in both time and frequency domains. The validity of the proposed modulation scheme is confirmed through the experiments. From a dual-parallel modulation experiment at 8GHz, a reduction of 23dB in IMD3 and the following increase of linear dynamic rage of 19.6dB are achieved compared to those of a single EML operation.
