Abstract
The inherent diffraction limited nature of classical optical tweezers[1] prevents their use for the trapping of particles smaller than a few hundred nanometres. Recent progresses in nanofabrication have facilitated the emergence of integrated devices capable of confining light beyond Abbe’s limit. This subwavelength confinement gives rise to large field gradients capable of generating unprecedented optomechanical forces on small dielectric particles[2].
