Abstract

The Dual Electroabsorption Modulated Laser (D-EML) is a transmitter technology specially design for dual drive. It is composed of an integrated Distributed Feed Back (DFB) laser and an Electro-Absorption Modulator (EAM) with dual independent modulation access. By controlling independently laser and modulator modulation amplitudes, it´s possible to adjust the chirp of this optical source and thus increase the transmission distance far beyond the chromatic dispersion limit. We develop a D-EML model based on experimental characterizations in order to study benefits of dual modulation scheme for optical systems at 10 Gb/s and above. In this paper, we propose to analyze the impact of the EAM chirp profile on the performances.
