We present a numerical modeling of a novel three-core fiber optic spanner. The spanner is realized by properly shaping the three-core fiber facet into a truncated triangular pyramid whose slope surfaces are not symmetric to the fiber cores. Three dimensional trapping forces and rotating torques are calculated and optimized as function of different parameters of the structure in ray optics regime. Simulation results show specific rotors can be trapped and rotated efficiently and stably by the spanner.
