Surface Plasmon Resonance-Based Fiber and Planar Waveguide Sensors

Figure 16

End-fire coupled SPP using a thin SPP waveguide. The optical fiber excites the SPP directly, and the metal grating ensures phase-matching [34]. By reducing the lateral dimension, one of the major problems of SPPs, that is, transmission loss, is greatly ameliorated and light can be coupled into the output fiber for making measurements.
