Abstract

An optical driven actuator has a feature of a non-contact for applying light energy remotely. A laser trapping and a laser manipulation for small particles are powerful tool for nano-micro bio-technology. Nowadays, vectorial vortex attracts the attention of a laser trapping and a laser manipulation for small particles because it can rotate the particle by polarization. In this paper, a spatially variant polarized beam called vectorial vortex array is proposed. The mechanism of generation of the spatially variant polarized beam is examined the properties of polarization on beam profile. The generation mechanism of the beam consists of phenomena of the polarization and the interference. The vectorial vortex array is converted to different spatially variant polarized beams by adding a half wave plate. Their polarized beams are shown in experimentally.
