Zero-bias and low-chirp, monolithically integrated 10 Gbit/s DFB laser and electroabsorption modulator on semi-insulating InP substrate

摘要

A DFB-laser monolithically integrated with a short (150 /spl mu/m) bulk electroabsorption (EA) modulator has been developed on a semi-insulating substrate. An extinction ratio of 10 dB for 0 to -2 V modulation was obtained with low chirp. Penalty-free 10 Gbit/s transmission over 41 km standard fibre, and 2.5 dB penalty over 71 km standard fibre was achieved.
