Magneto optical Sandwiches for Surface Plasmon Resoannce Systems

Original language description

Abstract - The Au/Fe grating/Au sandwiches located on BK-7 substrate have been applied in Otto configuration for magneto-optical (MO) surface plasmon resonance sensor units. We analyzed the reflectance and Kerr magnetooptical parameters of used structurefor different periodicity and thickness of golden films. The height of Fe dots placed in Au matrix has been fixed at 20 nm, the laser incidence beam was ppolarized at the wavelength of 632.8 nm. The results show the sharp reflectance extreme (up to Rp =0.85) as the function of incidence angle. This dependence is importantly modified by Au film thickness. The influence of magneto-optical activity of Fe grating has been studied by Kerr effect in longitudinal configuration. The maximum of rotation achieves is 4 mdeg, the extreme ellipticity value is about 3 mdeg. The influence of Au film thickness on Kerr parameters is observed too. The achieved results offer new approaches for MO surface plasmon resonance sensing elements. .
