Abstract
Lasers with integrated electroabsorption (EA) modulators are showing a lot of promise as low-chirp sources for long-haul transmission systems at multigigabit-per-second speeds.1,2 There are various structures and growth techniques for making such devices.3·4 Here we demonstrate a multiple-quantum-well (MQW) DBR-LD/EA modulator in a 495-km transmission system operating at 2.5 Gbit/s.
