Abstract:	The influence of built-in polarization on electronic blocking layer for InGaN quantum-well lasers is numerically studied by employing an advanced device simulation program. The simulation results indicate that electron overflow of InGaN quantum-well laser can be reduced by using the AlInGaN electronic blocking layer. When the aluminum and indium compositions in AlInGaN electronic blocking layer are appropriately designed, the built-in charge density at the interface between InGaN barrier and AlInGaN electronic blocking layer can be reduced. Consequently, the electron leakage and threshold current can be decreased when the built-in polarization is taken into account in our simulation. Furthermore, higher quantum-well optical confinement factor can be obtained by using the AlInGaN electronic blocking layer.
