摘要：

1.27mum InGaAs:Sb-GaAs-GaAsP vertical cavity surface-emitting lasers (VCSELs) were grown by metalorganic chemical vapor deposition (MOCVD) with superior performance. The threshold current changes between 1.8 and 1.1 mA and the slope efficiency drops below similar to35% when the temperature is raised from room temperature to 70degreesC. With only 5 mA of bias current, the 3 dB modulation frequency response is measured to be 8.36 GHz which is suitable for 10Gb/s operation. The maximal bandwidth is estimated to 10.7GHz with modulation current efficiency factor MCEF) of similar to5.25GHz/(mA)(1/2). The results of InGaAs:Sb-GaAs-GaAsP VCSELs can reach a performance level comparable to GalnAsN VCSELs with better thermal stability and should be considered as a very promising candidate for 1.3 mum commercial applications.
