We report for the first time the use of photopolymerizable liquid crystals in fabricating microsized cylinders that are rotated by a circularly polarized laser beam. They were fabricated by two-photon photopolymerization from liquid crystals whose molecules had been deliberately oriented on a rubbed surface. The rotational torque showed similar oscillatory structures to those observed in the intensity of light transmitted through crossed Nikols as a function of cylinder height. From the structures, the birefringence of the cylinders was estimated and the main mechanism underlying the rotational torque transfer was determined.
