Abstract
To overcome a trade-off issue between stability and flexibility in the generation of ring-shaped optical lattices, we proposed and demonstrated a novel generation method by using axially symmetric polarization elements. While two optical vortices were coaxially generated, electrically controlled phase difference between them by an electro-optic modulator enabled a precise rotation of the lattice. Our method has the capability to fulfill the high stability and rapid rotation.
