Abstract
Collective character of molecular interaction in liquid crystals creates an intrinsic feedback mechanism. Two co- propagating noncoherent beams of orthogonal polarization produce strong molecular orientation switching and optical bistability without additional external fields and feedback. The angular momentum of the combined light is easily controlled, and a light-driven molecular motor is demonstrated.
