PLASMON RESONANCE STRUCTURE, PLASMON RESONANCE SENSOR AND PLASMON RESONANCE MEASUREMENT SYSTEM USING THE SAME, AND METHOD FOR MANUFACTURING PLASMON RESONANCE STRUCTURE

摘要

To provide a plasmon resonance structure which can excite plasmon resonances with two different wavelengths by an emission of one polarization.SOLUTION: A plasmon resonance structure 10 includes a substrate 11 and a metal layer 14. The metal layer 14 includes a nano-structure 21, a nano-structure 22 larger in size than the nano structure 21, and a frame 25 surrounding the nano structures 21 and 22 and electrically connecting the nano-structures 21 and 22 to each other. The nano-structure 21 has a sharp part T1 and the nano-structure 22 has a sharp part T2. The nano-structures 21 and 22 are arranged so that the sharp parts T1 and T2 face each other.SELECTED DRAWING: Figure 3
