Surface Plasmon Resonance (SPR) technique has been widely accepted as a standard tool for the optical characterisation of interfaces and thin films. An indigenously developed multipurpose table top SPR measurement setup has been exploitedto fabricate optical magnetic field sensors using magneto-optic kerr effect (MOKE). Otto ATR configuration in SPR is a very rapid and sensitive technique to examine the multilayered interfaces also. Ferroelectric materials have proved their potential in the fabrication of electro-optic (EO) modulators due to the high value of dielectric constants and electro-optic properties. SPR technology when combined with an EO material leads to the development of highly efficient optical light modulators due to high sensitivity towards the change in refractive index at the interface, This electro-optically modulated SPR detection process possess interesting features such as potentially reduced noise level and more immune to power drifts.Experimental results and theoretical simulations on the study of EO and MO properties using SPR technique are prevented.
