Effect of rectangular aluminum nanoantennas on the optical emission of GeSiSn/Si multiple quantum wells
The spectral positions of a localized surface plasmon resonance in the rectangular aluminum nanoantenna arrays formed on the surface of emitting heterostructures with GeSiSn/Si quantum wells are determined using FTIR reflectance and reflectance anisotropy spectroscopy. It is shown that the interaction of nanoantennas with the optical radiation of GeSiSn/Si leads to its partial polarization. An enhancement of the heterostructures’ photoluminescence intensity is also demonstrated, depending on the spectral overlap of the radiation ranges of multiple quantum wells and the localized surface plasmon resonance in the nanoantennas.
