Abstract
Based on numerical experimental techniques, we demonstrate the possibility to control light by light in nonlinear arrays of subwavelength dielectric parallel waveguides. To reach our goal, we work with waveguides of different cross sections: circular and square. Characteristic dimensions of waveguides are in the order of half of the carrier wavelength, and propagation distances are more than hundreds of wavelengths. We show that with the proper selection of parameters it is possible to obtain light self-trapped in a single waveguide that will allow us to study the optical fields’ interaction in the array. The main result that we discuss here is that we can control the light output position for two input beams. The light behavior is a function of the phase difference and incidence angle, as well as the light power at the input of the array.
