Investigating the use of a hybrid plasmonic-photonic nanoresonator for optical trapping using finite-difference time-domain method (2016)
Journal Article

We investigate the use of a hybrid nanoresonator comprising a photonic crystal (PhC) cavity coupled to a plasmonic bowtie nanoantenna (BNA) for the optical trapping of nanoparticles in water. Using finite-difference time-domain simulations, we show t...
