Abstract :
GaInNAs lasers grown on GaAs substrates are very attractive for the application of uncooled operation with high performance at 1.3 mum region. However, fundamental material and device properties which are important for device design are still not fully understood. In this paper, we investigated temperature dependence of laser and light emitting diode (LED) characteristics for this purpose. We found that the threshold current density (Jth) of GalnNAs laser was considerably lower than that of GaInAs laser at low temperature, although it is much higher at room temperature
