Abstract
We investigate optical bistability with light beams propagating in reorientational nematic liquid crystals. In a given interval of input powers, light beams can propagate in either diffracting or soliton states, depending on the “history” of the system. We use biased planar samples exhibiting an abrupt self-focusing response with threshold.
