This brief investigates the role of photon flux density and photon energy in photon-driven quantum tunneling. Using a simplified exponential model and numerical simulations, the study demonstrates that photon flux density overwhelmingly dominates tunneling probability, with photon energy playing a secondary role. The findings suggest that optimizing flux density is the most effective strategy for enhancing tunneling effects in practical applications. Visualizations and quantitative comparisons illustrate the exponential impact of flux density relative to photon energy across various barrier thicknesses and energy ranges. This work has implications for advancements in quantum devices, photonics, and tunneling phenomena.
