Abstract :
Fabry-Perot and distributed feedback spot size converted 1.3 /spl mu/m lasers are demonstrated with competitive performance (/spl sim/10 mA threshold, >0.30 W/A slope) and narrow (16/spl times/9) far fields capable of coupling 45% of the output light into flat cleaved fiber. The Fabry-Perot device demonstrated error-floor-free transmission at 85/spl deg/C with a wide-open eye, uncooled 2.5 Gb/s operation up to 85/spl deg/C, and reliability of 105 FITS at 50/spl deg/C. The DFB devices have good DC performance with side mode suppression ratios of >40 dB. These devices will allow passive alignment and packaging without the need for intervening optics.
