Abstract

The Dual Electro-absorption Modulated Laser (D-EML) is a transmitter technology based on integrated Electro-absorption Modulated Laser (EML) with dual independent-access modulation. The D-EML allows the adjustment of the laser and modulator chirp by controlling the amplitude modulation in order to enhance the transmission distance without increasing consumption, cost and complexity. We successfully demonstrate experimentally and by simulation an error-free 39.7-km transmission at 20 Gb/s in standard dispersion fiber without any compensation fiber using D-EML.
