We investigate the functioning of an innovative monolithically integrated surface plasmon resonance (SPR) device comprising a metal coated SiO2 layer deposited atop a photoluminescence emitting quantum well (QW) wafer. The device takes advantage of the uncollimated and incoherent emission of QW microstructure. This presents a non-trivial problem in our goal to describe quantitatively the functioning of such a device. We discuss the results of our calculations based on a rigorous coupled-wave analysis algorithm and tensorial approach aimed at the full description of surface plasmons (SPs) coupling in QW semiconductor-based SPR architectures designed for biosensing applications. The results indicate that the injected in-plane wavevectors increase the SPs coupling efficiency up to 103 times in comparison to indirect SPs injection. We discuss the general idea of an experimental setup required for collecting the 3D measurement of SPR dispersion relations hω(kx,ky), potentially enabling a much richer picture of surficial biochemical events. Preliminary results indicate that the proposed methodology produces simultaneously the equivalent of 105 to 108 conventional SPR scans achievable with commercial systems.
