In this work we developed new type of biosensors based on nanolayered metal-dielectric structure. It was found that using the combination of nano-size (from 15 to 25 nm) layers of gold and dielectric support a new type of plasmon modes: bulk plasmon-polariton (BPP). In this work the role of corrugation for different nano-layers has been investigated. Thus, it was found that even corrugation of one 25 nm nano-layer results in effective coupling of BPP modes. The coupling efficiency as a function of corrugation depth, corrugation profile has been investigated. Diffraction gratings were fabricated by hot embossing technology.
