【 摘 要 】

Based in the numerical experiment techniques, we study the propagation dynamics of electromagnetic waves along one-dimensional array of parallel cylindrical subwavelength waveguides, possessing Kerr nonlinearity. By means of the proper selection of the array parameters, as well as the incident radiation properties and applying the Finite Difference Time Domain method, we are able to observe the light self-trapping in one single subwavelength waveguide. Furthermore, the position of the output beam can be controlled by the phase difference and the angle of incidence of the input beams. These results could give the possibility to control light by light, with perspectives in applications to implement integrated optics devices at nanoscale.
