Strain sensors based on Fano resonance in plasmomechanical system
Résumé
Due to their unique plasmonic and mechanical properties, plasmomechanical systems have become thoroughly investigated for strain sensing applications. The realization of strain sensors with high performance requires plasmonic resonances with high quality Factor (Q) such as Fano resonances (FR). In this respect, wehave carried out an optomechanical study of a plasmomechanical system supporting FR, consisting of two gold nanoparticles (GNs), a disk and a rod, deposited on a polydimethylsiloxane (PDMS) substrate.
