This paper gives a comprehensive theoretical study of microwave-to-optical conversion, which is critical for advances in future sensor networks and the quantum Internet of Things (IoT), We focus on six-wave mixing and use a density matrix approach to investigate the interaction between atomic ensembles and optical fields. The Master equation is used in the study to simulate these interactions, and MATLAB is used to calculate the steady-state solutions of the optical Bloch equations numerically. This research contributes to understanding Electromagnetically Induced Transparency (EIT) in these conversion processes. In doing so, we give essential insight into maximizing the conversion efficiency between microwave and optical frequencies, a critical factor in improving data transmission capacities across a wide range of applications.
