In this research, we demonstrate an optical vortex array using the smectic liquid crystal called Toric Focal Conic Domains (TFCDs). A regularly organized TFCD array in a large area was fabricated, followed by optical characterizations with the polarized optical microscope and the laser interferometry. © 2012 IEEE.
