Abstract
The influence of magnetic field on Ψ(λ) and Δ(λ) dependences of Al-based plasmon-polariton photodetectors (PPPD) at different magnetic flux densities (100 and 300 mT) and magnetic field directions was investigated. It was obtained that the action of the magnetic field results in the shift of the surface plasmon resonance peak (SPR) position and a change in its intensity. Particularly, in the configuration ( and are collinear) the noted effects were the most pronounced. Additionally, it was found that the magnetic-induced effects are sensitive to the angle of incidence, particularly they enhance with decreasing the angle of incidence. Therefore, they were the most pronounced at the smallest angle in our experiment (20°). The possible physical mechanisms of observed phenomena are discussed. The obtained results can open up new opportunities in the design of optoelectronic sensors of the magnetic field or high-speed optical modulators.
