Abstract

We study experimentally self-trapping of optical beams in photorefractive media and show that the trapping is inherently asymmetric with respect to the two (transverse) trapping dimensions. We also present experimental results that show how the sizes of the resultant photorefractive spatial solitons are independent (within their range of existence) of the amplitude of the externally applied electric field used to generate them.

Horizontal and vertical profiles of input (upper), diffracted output (middle), and self-trapped (lower) beams of (a) 35-μm and (b) 85-μm minimal waists, which are located at the input plane. The waveforms are normalized to the maximal amplitudes, and the spot sizes are determined through a Gaussian fit.

Horizontal and vertical profiles of input (upper), diffracted output (middle), and self-trapped (lower) beams with a similar spot size (~80 μm) but with different radii of curvature [(a) infinity, (b) 4 mm] at the entrance face. The waveforms are normalized to the maximal amplitudes, and the spot sizes are determined through a Gaussian fit.
