Here, we present results we have achieved using SPR scattering as an alternative approach for optical fiber based plasmonic sensors. Although the use of a rough metallic coating induces some inherent limitations, such as a lower resolution, the architectural advantages and simplicity of the approach offer additional opportunities, such as multiplexing and self-referencing, which are not possible otherwise with a single fiber SPR sensor. A way to overcome the lower resolution that involves the use of microstructured optical fibers, as well as a new perspective on a complementary application, such as Metal Enhanced Fluorescence, which greatly benefits from SPR scattering, will be presented.
