Plasmon-polariton photodetectors of the Schottky barrier type have been manufactured, which showed a high value of the polarization sensitivity coefficient Ip / Is = 4.5. The features of the excitation of surface local plasmons (LP) and surface plasmon polaritons (SPPs) in diffraction gratings in the form of a periodic array of gold nanowires on dielectric (glass) substrates covered with an additional thin film of gold have been investigated. It was found that when the thickness of such a film is increased, there is a transition from excitation of LP in nanowires to excitation of the SPP. In addition, there is a redistribution of energy between the LP and the SPP when changing the geometric parameters of nanowires, which may be relevant for fine tuning of sensory elements.
