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.
