Abstract: The invention is a SPR sensor that comprises a multi-layered plasmonic structure on a substrate for sensing. The SPR sensor has an enhanced figure of merit and lower limit of detection (system noise divided by the sensitivity) by at least two orders of magnitude than prior art SPR sensors. The plasmonic structure of the invention comprises a Nano-structured Porous Metal Layer (NPML) and at least one of: (a) buried dielectric layer under the nano-porous metal layer; (b) a nano-dimensional high index layer on top of the metal layer; and (c) a molecular layer for bio-functionalization adjacent to an analyte layer. The invention also encompasses many embodiments of measuring systems that comprise the SPR sensors of the invention with improved signal to noise ratio.

Abstract: Herein is provided a simplified method for performing multiple wavelength phase shift interferometry measurements that is implemented by modulating each of the monochromatic light sources with a different carrier frequency, combining them to a single beam, detecting all wavelengths simultaneously using the same detectors and separating them via Fourier analysis and demodulation of the data. This approach offers both a simplification to the optical system and reduces the duration of time required to perform the multiple wavelength measurement, based on a simple data extraction algorithm decoding the information for each wavelength. When combined with the parallel phase shift orthogonal polarization interferometric microscopy this method provides fast, stable, high precision 3D imaging and displacements sensing. Also disclosed are embodiments of optical systems designed to carry out the method.
