N2 - We experimentally demonstrate a stretchable plasmonic structurecomposed of a monolayer array of gold semishells with dielectric coreson an elastic PDMS substrate. The composite structure is fabricated usingsimple and inexpensive self-assembly and transfer-printing techniques,and it supports Bragg-type surface plasmon resonances whose frequenciesare sensitive to the arrangement of the metallic semishells. Under uniaxialstretching, the lattice symmetry of this plasmonic structure can be reconfiguredfrom hexagonal to monoclinic, leading to resonance frequency shiftsfrom 200 THz to 191 THz for the TM polarization and from 200 THz to198 THz for the TE polarization with a strain up to 20%, respectively.Compared with previously reported tunable plasmonic structures, thereconfiguration of lattice symmetry offers a promising approach to tune thesurface plasmon resonance with a polarization-dependent response at thestandard telecommunication band, and such tunable plasmonic structuremight be exploited in realizing photonic devices such as sensors, switchesand filters.
