Wide temperature range (0 to 85/spl deg/C), 40-km SMF transmission of a 1.55 /spl mu/m, 10-Gbit/s InGaAlAs electroabsorption modulator integrated DFB laser

A new uncooled 1.55 /spl mu/m InGaAlAs electroabsorption-modulator integrated DFB-laser suitable for low-power-consumption 10-Gbit/s small-form-factor modules is demonstrated. For the first time, 10-Gbit/s 40-km normal SMF transmission with 1-dB power penalty is achieved from 0 to 85/spl deg/C.
