Optical trapping via guided resonance modes in a Slot-Suzuki-phase photonic crystal lattice.

ABSTRACT

A novel photonic crystal lattice is proposed for trapping a two-dimensional array of particles. The lattice is created by introducing a rectangular slot in each unit cell of the Suzuki-Phase lattice to enhance the light confinement of guided resonance modes. Large quality factors on the order of 105 are predicted in the lattice. A significant decrease of the optical power required for optical trapping can be achieved compared to our previous design.
