Plasmonic devices are among the most sensitive contemporary sensors of chemical or biological analytes, in some
cases even reaching single molecule sensitivity. These are refractometric devices making use of extreme light concentrations
and offering real-time, label-free operation. For their proper operation one needs efficient coupling between the
propagating interrogation beam and bound surface plasmons polaritons (SPP) whose wave vector is much larger. An
external prism in Kretchmann or Otto configuration can be used for such coupling, or some kind of diffraction coupler or
fiber-based endfire coupler. In this contribution we investigate theoretically and experimentally possibilities to fabricate
sensor structures that simultaneously exhibit plasmonic properties and ensure diffraction-based coupling. To this purpose
we fabricated different micrometer-sized two-dimensional metal-dielectric arrays that can match wave vectors of
propagating beams and of SPP and at the s...ame time show plasmonic properties tunable by design. We investigated
structures functioning in reflection or in transmission mode, with gold or aluminum as the basic material and with deep
subwavelength details. Our structures can be made much more compact than the conventional ones, thus being convenient
for monolithic on-chip integration with light source and detector and offering a larger degree of design freedom for
multianalyte CORN sensing.
