Several of the refractive index models we consider admit so-called
bistable solitons, light bullets with the same energy content but radically
different radial profiles. For example, the pulses in the first
image below contain the
same energy content despite their grossly disparate sizes. This
is possible because the smaller bullet has a much more intense center
with respect to the larger soliton. This simulation depicts a collision
between two such bistable light bullets, the smaller bullet burrowing
through the middle of the larger diffuse bullet.
