Abstract

We experimentally demonstrate guiding of a low-power probe beam (633 nm wavelength) by means of a light-induced waveguide generated by the self-focusing of a strong pump beam (532 nm wavelength) in an artificial nonlinear medium, constituted by a colloidal suspension of dielectric nanoparticles. We also demonstrate optical steering of the probe beam by controlling the direction of propagation of the pump beam. The distance over which guiding is demonstrated (5 mm) is remarkably long when compared with previous experiments.

Fig. 1.

Experimental setup. Beam expander (BE); mirrors (M1, M2 and M3); beam combiners (BC1 and BC2); microscope objective (MO); cell containing the nonlinear medium (NLM); beam block (BB); color CCD camera on a translation stage (CCD). Mirror M1 can be displaced to control the direction of propagation of the pump beam at the focal plane of MO.

Fig. 2.

Images of the output pump beam (top row) and of the probe beam when the pump is off (middle row) and on (bottom row). Left (right) column corresponds to a pump power of 939 mW (1266 mW). A white-cross marker indicates the intensity centroid in each case. The white curves show vertical and horizontal intensity profiles in each image. The intensity in the images of the central row was multiplied by a factor of 3 to make them visible.

Fig. 3.
Fig. 3.

From top to bottom: probe beam in absence of the pump beam; probe beam guided by the pump beam propagating at angles of deflection of 1.8°, 0°, and 1.8°, respectively, for a pump power of 1434 mW. The centroid in each case is indicated with a white-cross, and the white curves show vertical and horizontal intensity profiles. The dotted line shows the position of the centroid of the nonguided probe beam. The intensity in the top image was multiplied by a factor of 3 to make it visible.

Power gain of the guided probe beam when compared with the nonguided probe beam, for an aperture of fixed radius, as a function of angle of deviation for different pump powers. Dotted line (red): 939 mW; dash-dot line (green): 1123 mW; solid line (blue): 1266 mW; dashed line (black): 1434 mW.
