Abstract

In this article, the laser performance of the 1300-nm In 0.4Ga0.6As0.986N0.014/GaAs 1 - xNx quantum-well (QW) lasers with various GaAs 1 - xNx strain compensated barriers (x = 0%, 0.5%, 1%, and 2%) has been numerically investigated with a laser technology integrated simulation program. The simulation results suggest that with x = 0% and 0.5% can have better optical gain properties and high characteristic temperature coefficient T0 values of 110 and 94 K at the temperature range of 300-370 K. As the nitrogen composition in GaAs1 - xNx barrier increases more than 1% the laser performance degrades rapidly and the T0 value decreases to 87 K at temperature range of 300-340 K. This can be attributed to the decrease of conduction band carrier confinement potential between In0.4Ga0.6As0.986N 0.014 QW and GaAs1 - xNx barrier and the increase of electronic leakage current. Finally, the temperature dependent electronic leakage current in the InGaAsN/GaAs1 - xNx quantum-well lasers are also investigated.
