The present document describes the simulation, development and characterization of a custom implementation of optical resonant sensors, with high throughput capabilities while acting as chemical or label-free biosensors. Opti- FDTD 9.0 software has been used with the aim of simulating the diffractive resonant structures of interest. By means of holography, it has been possible to create large active areas of about 1cm^2, which allows a theoretically unlimited number of measurement channels. State of the art bulk sensitivities in the order of 136nm/RIU have been found, in agreement with the results obtained by dint of simulating a model of the fabricated structure.
