Data is reported on 1.3 micrometer uncooled MQW DFB lasers and OC-12(622Mbps) optical transmitter modules. The devices show stable single longitudinal mode operation up to a maximum output power of 100mW with a SMSR greater than 46dB and the characteristic temperature measured continuously between 20 and 80 degrees Celsius is 78K. An average optical power of -2dBm and an extinction ratio of 14 dB were obtained from the OC-12 transmitter module with the DFB laser.
