The concept of an integrated nanoplasmonic sensor implemented on a silicon substrate is presented. Developed experimental setup based on rotation of linearly polarized light provides intensity detection between two orthogonal polarizations of a He-Ne laser beam. This optical configuration yields to a sensitivity improvement and noise reduction, resulting in a resolution of 4x10(-5) Refractive Index Units. Proposed methodology is promising for the application in portable nanoplasmonic multisensing and imaging.
