Photonic crystals (PhC) are optical nanostructures that are widely known for their strong spatial and temporal confinement of electromagnetic radiation. Here, we study the resonant optical trapping of a single nanoparticle within a hollow circular photonic crystal cavity. The Electromagnetic Waves (emw) interface of COMSOL Multiphysics® was extensively used during the analysis of all our experimental results. Adaptive meshing strategies were employed to handle the difference in the largest and smallest features involved in the system. Our numerical results have complimented both qualitatively and quantitatively with our experimental results. These exciting results provide the basis for further analysis of the dynamics of a single particle within a resonant trap and the study of anharmonic force profiles.
