Gold Bowtie-Shaped Dimer Arrays in a Stretchable Substrate with Tunable LSPR

We proposed and demonstrated a gold bowtie-shaped dimer array semi-buried in a deformable polymer substrate. The wavelength tunability of coupled bonding localized surface plasmon resonance modes with different polarizations was confirmed by stretching simulations and experiments. The tuning operati...

Description
Summary:We proposed and demonstrated a gold bowtie-shaped dimer array semi-buried in a deformable polymer substrate. The wavelength tunability of coupled bonding localized surface plasmon resonance modes with different polarizations was confirmed by stretching simulations and experiments. The tuning operations were reconfigurable and reliable under applied elongations of up to 50%.
