In this study, we report the effects of the exciton line widths on the amplitude of quantum beat oscillations using a model with the Voigt function. Using the Voigt function, we find that the maximum amplitude appears at the central energy between two excitons. This result agrees with many previous experimental results. Our analysis helps in identifying the condition for strong quantum beat oscillation, which is important for device applications such as terahertz electromagnetic wave emitters and ultrafast switches.
