Abstract

In this letter, we investigate the yield of 10-Gb/s electroabsorption modulator integrated-distributed feedback (EAMI-DFB) lasers for 40- and 60-km transmissions due to the chirp. The yield has been estimated from the effective positive chirp (EPC) capable to transmit signals over 40 and 60 km within 2-dB dispersion power penalty. The signals with EPC of 0.48 and 0.24 Å can be transmitted over 40 and 60 km with less than 2-dB power penalty, respectively. The chirp is calculated from a large signal dynamic model of EAMI-DFB lasers using the time-dependent transfer matrix method (TMM). The results suggest that the yield is mostly dependent on coupling constant (κL) and should be set around 1.3 for high yield while maintaining low facet reflectivity at modulator.
