Paper Abstract

Dynamic control of light by surface plasmon resonance is applicable for mechanically tunable photonic devices, such as variable color filters, tunable Neutral Density (ND) filters, and adjustable surface-enhanced Raman scattering (SERS) substrates. We experimentally demonstrated dynamic tuning of plasmon resonance using the strain-controlled elastic device of close-packed gold nanoparticle array that was fabricated by self-organized technique. By applying the uniaxial strain, the plasmon peak wavelength blue-shift of 23 nm under parallel polarization to the strain direction and red-shift of 27 nm under perpendicular polarization, and the total tunable range was achieved to 50 nm. In addition, by applying the biaxial strain, peak shifts in the strain are monotonic for both linear polarizations, which is clear advantages for practical optical applications.
