Spectral hole burning of surface plasmon polaritons via soliton waves at the interface of sodium and gold media

Abstract

We investigate the possibility of creating spectral hole burning in surface plasmon polaritons (SPPs) at the interface of sodium vapor and gold media. The spectral holes are measured at specific parameters, phases and directions of the control fields. The direction and phase of the control field affect the creation of spectral hole burning in SPPs the most. The pulse shape in the spectral burning hole region is uniform and undistorted due to the cancellation of nonlinear Doppler broadening and large group velocity dispersion. The behavior of SPPs pulse in the spectral hole region is that of solitons, which arise due to cancellation of large positive dispersion for phase shift with nonlinear effect.. The results may have potential applications in nano-photonics, plasmonsters, photovoltaic devices, cloaking and sensing technology.

Tunable transverse-electric surface plasmon polariton waves in a parallel-plate graphene-based waveguide

“…The research field of plasmonics [1,2] particularly metalbased plasmonic [3,4], and graphene plasmonic waveguides [5][6][7][8] is growing rapidly, involving the generation and propagation of surface plasmons (SPs) in linear and nonlinear media. SPs are coherent fluctuations of surface charge density between a conductor and a dielectric medium [9].…”
