| description | We present in this study a theoretical investigation of the near-field enhancement phenomenon within nanostructures, which have garnered recent attention due to their potential applications in sensing, imaging, and energy harvesting. The analysis reveals a significant intensification of electromagnetic fields proximal to periodically arranged arrays of gold nanoparticles sustaining a highly lossy mode. In addition to the existence of a localized surface plasmon (LSP) mode exhibiting suboptimal quality, our investigation unveils intricate aspects of near-field enhancement closely correlated to the dynamics of lasing mechanisms. Notably, our investigation is focused on elucidating the augmentation’s behavior across varying pumping energies. The achieved enhancement surpasses two orders of magnitude compared to the passive counterparts. We introduce a description of the energy conversion rate specific to the SPASER configuration. The conceptualized SPASER reveals a significant promise. It showcases energy conversion efficiency up to 80%, emphasizing the SPASER’s potential as a highly effective nano-scale energy source. |
