Paper Abstract

Large scale, dense arrays of plasmonic nanodisks (Au) on low modulus, high elongation elastomeric substrates (PDMS) represent a class of tunable optical system, with reversible ability to shift plasmon resonances, originating from array deformation, over a range of nearly 600nm in the visible region. At the most extreme levels of mechanical deformation (strains <100%), non-linear buckling processes transform initially planar arrays into three dimensional configurations, in which the nanodisks rotate out of the plane, giving rise to an increase of transition rate, to form linear arrays with ‘wavy’ geometries. Analytical and finite element models capture not only the physics of these buckling processes, including all of distinct modes that occur, but also the quantitative effects of these deformations on the plasmonic responses. The results have relevance to mechanically tunable optical systems, with potential relevance to soft optical sensors that integrate on or in the human body.
