摘要: In this work, the multiple-quantum-well InGaAsN
laser structures with indirect-GaAsP and direct-GaAsN barriers
are investigated by using LASTIP simulation program.
We vary the quantum-well number, from 1 to 5, to find
appropriate barrier material for InGaAsN laser structures.
The simulation results show that InGaAsN laser structure
has higher characteristic temperature regardless of what
quantum-well number is if the indirect-GaAsP barrier is
utilized. Furthermore, for InGaAsN laser structure, the usage
of indirect-GaAsP barrier is beneficial for reducing the
threshold current when the quantum-well number is from
1 to 2 and the usage of direct-GaAsN barrier is beneficial
for reducing the threshold current when the quantum-well
number is from 3 to 5.
