A1 .3-m-range uncooled electroabsorption/dis- tributed-feedback (EA/DFB) laser was demonstrated. Incorpo- rating an InGaAlAs multiple quantum well (MQW) modulator, a low-capacitance structure, and butt-joint integration, this laser successfully demonstrated 43-Gb/s 10-km transmission for the first time. The developed laser achieved clearly opened eye di- agrams with dynamic extinction ratio of over 7 dB over a wide temperature range (25 Ct o 85 C). Index Terms—Electroabsorption (EA) modulator integrated distributed feedback (DFB) laser, 40-Gb/s light source, uncooled operation.
