Abstract
Experimental observation and numerical results concerning collisions between scalar and vector spatial solitons in a Kerr planar waveguide are presented. It is shown that this configuration allows for the full control of spatial and polarization dynamics of the interacting vector solitons. On the one hand, the ability to achieve polarization control of a single-hump vector soliton is demonstrated. On the other hand, the effect of collision on the spatial symmetry-breaking dynamics of multimode vector solitons is investigated.
Highlights
Self-guided light beams result from the balance between linear diffractive and self-focusing effects induced in a nonlinear medium (Kivshar and Agrawal 2003)
Our results show that collision between vector and scalar solitons gives rise to new spatial or polarization dynamics that could be useful for realizing various all-optical switching functionalities
We reported two examples of vector soliton collision in isotropic Kerr media
Summary
Self-guided light beams result from the balance between linear diffractive and self-focusing effects induced in a nonlinear medium (Kivshar and Agrawal 2003). They have raised a lot of interest because of their ability to guide themselves and other beams, while being fully configurable (Kivshar and Stegeman 2002). The spatial symmetry-breaking of multimode vector solitons in Kerr media spontaneously generates a waveguiding structure merging several channels to one (Silberberg and Barad 1995; Haelterman and Sheppard 1994a; Kockaert and Haelterman 1999).
