Surface Plasmon Resonance-Based Fiber and Planar Waveguide Sensors

<table>GM is the guided mode, and<b> A </b>is an attenuator. Insertion illustrates the MZI branch with the Bragg grating. The other MZI branch is identical to the shown one, but without the grating. The SPP travels in the opposite direction if an LPG is used.</table>
