  • any direct transmission of light. The grating was designed to couple normally incident light at � 0 � 532 nm to a surface-plasmon wave, while the Bragg grating with a central defect serves as a plasmonic microcavity for the surface wave. Therefore, the actual coupler period and the Bragg period were chosen to be 0.5 and 0:25 � m, respectively. The outer diameter of the structure was 10 � m and the small radius of the spiral cavity was chosen to be r0 � 1:2 � m. These parameters are also consistent with the
