10 km transmission using an uncooled Be-doped Fabry-Perot laser with more than 100-degree operation temperature range

Uncooled operation for a FP laser is presented. More than 100-degree temperature operation range was achieved for 10 km/2.5 Gb/s. The lasers were fabricated using Al/Zn-free InAsP/InP design for good reliability. Frequency response of 7 GHz at -25/spl deg/C and 5.2 GHz at 85/spl deg/C was measured for TO56 can package.
