摘      要：The surface plasmon resonance tracking over metal surfaces is a well-established,commercially available,biochemical quantification tool primarily applied in *** utilization of such a tool is,however,constrained to highly specialized industries,capable of justifying the human and instrumental resource investments required by the characterization *** have proposed to expand the field of application of this biosensing approach by redesigning this method through the integration and miniaturization within a semiconductor *** and broadband emission from a light-emitting semiconductor is employed to couple a continuum of surface plasmon modes over a metal–dielectric architecture interfaced with a GaAs–AlGaAs substrate.A tensor version of rigorous coupled wave theory is employed to optimize the various fabrication specifications and to predict the light scatterings over a wide range of *** then present a hyperspectral characterization microscope capable of directly mapping the dispersion relation of scattered light,including diffracted surface plasmons,as an intensity distribution versus photon energy and surface *** carried out in a buffered solution demonstrate the accurate description of the uncollimated and broadband surface plasmon ***,we introduce a simplified method of dispersion mapping,in which quasi-conic cross-sections of the light’s scattering can be acquired directly,thus monitoring surficial responses in as fast as 1.2 *** is over 300 times faster than required by implementing full dispersion *** compromising on the volume of collected information,this method,combined with the solid-state integration of the platform,shows great promise for the fast detection of biochemical agents.
