“…(Experimental measurements have been projected onto tracing paper and photographed for surface-plasmon-coupled emission (SPCE) originating from fluorophores located in close proximately to a metallic surface. [22][23][24][25][26] Simulations of SPCE and waveguide-coupled SPP cones have been reported by Nils Calander 27 and Zhi-Mei Qi, 28,29 respectively. Calander's simulation was based on Fresnel's equations and the Weyl identity theorem for expressing the electromagnetic energy density of the SPCE from a dipole inside a thin polymer film.…”

Experimental data for waveguide-coupled surface-plasmon-polariton (SPP) cones generated from dielectric waveguides is presented. The results demonstrate a simpler route to collect plasmon waveguide resonance (i.e., PWR) data. In the reverse-Kretschmann configuration (illumination from the sample side) and Kretschmann configuration (illumination from the prism side), all the waveguide modes are excited simultaneously with p-or s-polarized incident light, which permits rapid acquisition of PWR data without the need to scan the incident angle or wavelength, in the former configuration. The concentric SPP cone properties depend on the thickness and index of refraction of the waveguide. The angular intensity pattern of the cone is well-matched to simulation results in the reverse-Kretschmann configuration, and is found to be dependent on the polarization of the incident light and the polarization of the waveguide mode. In the Kretschmann geometry, all waveguide-coupled SPP cones are measured at incident angles that produce attenuated light reflectivity. In addition, the enhanced electric field produced under total internal reflection allows high signal-to-noise ratio multimodal spectroscopies (e.g., Raman scattering, luminescence) to measure the chemical content of the waveguide film, which traditionally is not measured with PWR.

“…Since SPCE only has a coupling enhancement effect on molecules in the near‐field range, it has greater advantages in the detection of nano‐sized biological macromolecules such as nucleic acids [24,25] and proteins [26,27] . SPCE has the characteristics of directional emission, [28] wavelength resolution, [21] background suppression [29] and high‐level of P‐polarization, [19] which can effectively improve detection sensitivity and selectivity. Specifically, directional emission is the most basic feature of SPCE, that is, almost all signals are concentrated in one direction for radiation.…”

Surface Plasmon Coupled Directional Emission for Integrated Fluorescence‐Raman Biodetection: A Proof‐of‐Concept Study

The development of multi‐functional nanoplatforms has attracted much attention. The realization of fluorescence and Raman dual‐mode bio‐detection typically needs complicated switching procedures or algorithm processes. In this work, we propose that a surface plasmon coupled emission (SPCE) technique could be used to break the bottleneck. Our approach enabled Raman spectra which would normally suffer interfered by strong fluorescence signal to be distinguished, simply by respective measurements at different angles. As a proof of concept, we prepared dual‐mode nano‐composites for measurement. Herein, in SPCE, fluorescence was sharply distributed at 46° and Raman at 50°. Attributed to the unique directional radiation feature, collection efficiency increased dramatically, with nearly 5‐fold and 14‐fold absolute intensity enhancement compared to conventional fluorescence and Raman method. Meanwhile, Raman detectability could be improved dramatically in SPCE detection in contrast to free space measurement in one single wavelength excitation device, for serious fluorescence interference to Raman tags could be eliminated.
