  We consider the process of low-power light scattering by optical solitons in
a slab waveguide with homogeneous and inhomogeneous refractive index core. We
observe resonant reflection (Fano resonance) as well as resonant transmission
of light by optical solitons at certain incident angles. The resonance position
can be controlled experimentally by changing the soliton intensity and the
relative frequency detuning between the soliton and the probe light beams.
