Abstract

We report the experimental observation of the nonlinear interaction between two fundamental spatial solitons with a π/2 phase difference in carbon disulfide. An energy flow from the phase-advanced soliton to the phase-delayed soliton was observed, which leads to a single self-trapped beam. The position of the output beam can be switched by reversing the sign of the solitons’ initial phase difference.

Figures (3)

Fig. 1
Fig. 1

Numerical simulations of the interaction between two close fundamental solitons with a π/2 phase difference. The transverse coordinate is normalized to the soliton width, and the initial separation has been set to 1.7. In (a) the left-hand-side soliton has a phase delay, whereas in (b) the right-hand-side soliton has a phase delay. The intensity is in arbitrary units, and the propagation distance represents less than three soliton periods.

Fig. 2
Fig. 2

Fraction of the total power carried by the two input beams that is trapped into the single solitary wave versus the spatial solitons’ initial separation (normalized to their FWHM).

Fig. 3
Fig. 3

Comparison between the time-integrated recordings of (a) the input and (b), (c) the output transverse profiles. The output patterns are obtained after propagation through 37 mm of carbon disulfide. (b) shows the case in which at the input the left-hand-side soliton had a π/2 phase shift, and (c) shows the case in which the soliton had a −π/2 phase shift.
