A particle sorting scheme based on an optical vortex array

Abstract In recent years, the research and application of optical tweezers and their corresponding particle sorting has been constantly improving, and the application field is becoming more and more extensive. However, there are few reports regarding the theoretical and simulation study of particle sorting via optical vortex (OV). In this paper, we proposed an OV array (OVA) based particle sorting scheme. In this scheme, we utilized an OVA to act on the chamber filled with particle solution, and the key to successful particle sorting lies in different trapping capability among different row/column of OVA. The proposed scheme can provide a theoretical and simulation reference for practical experimental study and applications.
