Abstract:

We numerically investigate the interaction of vectorial solitary waves propagating in a bulk crystal with a phase-matchable quadratic nonlinearity. Coalescence, steering, crossing or repulsion are obtained by controlling the launched intensities in two orthogonal polarizations, without any coherent seed at the second harmonic.
