English abstract:
A novel platform for the detection of plasmonic resonance is proposed and demonstrated with silicon nitride trampoline nanomechanical resonator. Absorption cross section could be derived directly from the shift of the mechanical resonance frequency. As a proof of principle, gold bowtie nanostructures with various gap sizes were deposited with focused electron beam induced deposition onto the trampoline resonator, and scanned with laser-Doppler vibrometer. Finite-difference time domain simulations on bowtie nanostructures are also done for comparison, which shows a consistent trend with the measured absorption. With further optimization, this technique provides a simpler alternative for the identification of sub-wavelength nanostructures and optimization of plasmonic designs.
