In this paper, a concept of phase sensitive sensor based on plasmonic nanograting structures with normal incidence and transmission detection is presented. Performed theoretical modeling enables fabrication of nanostructures with optimal geometry for polarimetric measurements of the phase difference between s- and p- polarized light. High phase resolution of the optical setup (6*10(-3) deg.) allows detection of the bulk refractive index with sensitivity equal to 3.8*10(-6) RIU. Proposed technique presents a more efficient alternative to the conventional spectral interrogation method of nanoplasmonic-based sensing and could be used for multisensing or imaging applications. |
