Abstract :
We report optical trapping of 60 nm Au nanoparticles using photonic crystal slot-cavities with Q´s of ~7200 and 0.3mW of guided power at 1.6μm. Histograms of the cavity transmission are used to quantitatively analyze the trapping dynamics by modeling the back-action of the nanoparticles in the trap.
