Abstract
This study presents a theoretical analysis of the sensitivity of the surface plasmon polariton waves (SPPs) at a gain-assisted four-level N-type atomic system by exploiting the scheme of electromagnetically induced gain and propagation of the SPPs along the gain-assisted atomic-metal interface. The significant control over the sensitivity of the SPPs with system and driving field parameters, such as control and probe fields detuning, control field Rabi frequency, and decay rates, is reported. The sensitivity is the oscillation function of phase and decay rate, and the high value of sensitivity of the SPPs is examined to be 2000\(^{\circ }\)/RIU. The small value of sensitivity is noted to be 140\(^{\circ }\)/RIU with control fields Rabi frequencies. The modified result in this paper shows useful applications in biosensors, nano-photonic devices, and solar cells.
期刊介绍：
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
