Confinement Factor Calculations for SQW, SCH_SQW, MQW, and MMQW PbSe/PbSrSe Quantum Well Structures

摘要

In this study we present the theoretical formulas and calculations of optical energy that is confined in four nanostructures; namely Single Quantum Well Lasers (SQW), Separate Confinement Heterostructure_Single Quantum Well Lasers (SCH_SQW), Multiple Quantum Well Lasers (MQW), and Modified Multiple Quantum Well Lasers (MMQW). The material system used in this study is PbSe/Pb 0.934 Sr_(0.066) Se with non-parabolic energy band structure. The results of our analysis shows that the effects of including non-parabolicity on confinement factor calculation are lowering these values from its corresponding parabolic ones. Therefore, these effects should be taken into consideration when design a material system with similar band structures.
