Controllable branching of optical beams by quasi-two-dimensional dark spatial solitons

D. Neshev, A. Dreischuh, S. Dinev, and L. Windholz


A variable number of quasi-two-dimensional dark spatial solitons of adjustable transverse velocities could be generated by a proper choice of the initial phase profile (odd or even) and the width of the crossed dark stripes and the background-beam intensity. The possibility of branching a single input probe beam into ordered structures of subbeams is demonstrated numerically in a bulk self-induced-defocusing Kerr nonlinear media. The energy-density branching efficiency for each subbeam is evaluated and discussed.
