Abstract: The present invention relates to a new fluorescence detection platform based on the integration of grating-assisted surface plasmon coupled emission (GASPCE). This innovation builds upon the traditional SPCE technique by adding a grating to the metal surface which thereby provides additional emission confinement. The original conical emission pattern associated with the traditional SPCE technique is “squeezed” into a “two-beam” emission pattern that is more readily interrogated and collected by a waveguiding structure. With the GASPCE method and system of the present invention, a fluorescence emission can be coupled into optical waveguide with greater efficiency. As such, the integration of the GASPCE and existing optical fiber networking offers distributed real-time sensing capabilities. Also, the integration with an integrated optical chip may enable multi-channel array sensing or high-throughput florescence sensing.

Abstract: A cavity free, broadband approach for engineering photon emitter interactions via sub-wavelength confinement of optical fields near metallic nanostructures. When a single CdSe quantum dot (QD) is optically excited in close proximity to a silver nanowire (NW), emission from the QD couples directly to guided surface plasmons in the NW, causing the wire's ends to light up. Nonclassical photon correlations between the emission from the QD and the ends of the NW demonstrate that the latter stems from the generation of single, quantized plasmons. Results from a large number of devices show that the efficient coupling is accompanied by more than 2.5-fold enhancement of the QD spontaneous emission, in a good agreement with theoretical predictions.
