  While in linear optics the subject of structured light has been a fruitful
field of both theoretical and applied research, its development in the arena of
nonlinear optics has been underexplored. In this paper, we construct
Frozen-Wave-type structured optical beams in Kerr nonlinear media, emphasizing
the self-defocusing case, and use them to guide and control Gaussian optical
beams. The results presented in this study support the expectation that
structured light in nonlinear media can open new venues of theoretical research
and applications, particularly in the realms of light controlling light and for
all-optical photonics.
