A 1.3-µm InGaAlAs-MQW RWG DFB laser with low-resistance notch-free grating during operations of up to 12.5 Gb/s at 115 was fully investigated. This performance was achieved by combining the high differential gain of the InGaAlAs MQW active layer, high characteristic temperature of RWG structures, and low-resistance notch-free grating. In addition, transmission over 30-km was achieved with the laser running at up to 115. These results confirm the suitability of this type of laser for use as a cost-effective light source in 10-Gb/s datacom applications.
