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 validity of the proposed modulation scheme is confirmed through the simulations and experiments. From a dual-parallel modulation experiment at 8 GHz, a reduction of 23 dB in IMD3 and the following increase of linear dynamic range of 19.6 dB are achieved compared to those of a single EML operation.
