摘要
A report is made on the realisation for the first time of DFB GaInAs/AlGaInAs MQW active layer lasers with good static, dynamic and spectral performances; threshold currents as low as 13 mA are reported, and a maximum resonant frequency of 9.4 GHz is observed at only 6.6 mW power output. These values compare fairly well to those obtained with similar processes in the InGaAsP system and can probably be improved by a further optimisation of the structure.
