In that paper it is claimed that both bright and dark photorefractive solitons suffer from transverse instabilities and are unstable. But the experimental results presented in the same paper clearly show a "self-trapped channel of light" that does not exhibit transverse instabilities (Figs. 5d and 14b). Modulation instability was observed only when further "increasing the nonlinearity" (see discussion on page 874 there). The similarity between the experimental and the numerical results showing the development of the instability in that paper is misleading. The experimental results (Figs. 5 and 14) show sequences of output intensity distributions (at a fixed propagation distance) for different levels of applied voltages (i.e., different levels of nonlinearity), only one of which corresponds to that of a soliton (is on the existence curve), whereas the simulations (Figs. 1 and 9) show the near-field intensity evolution for different propagation distances for a fixed set of parameters (i.e., at a fixed voltage) that greatly differ from that of a soliton.
