Properties of Optical Vortex Lattice Generated via Multiple Plane Wave Interference
Multiple plane wave interference (MPWI) is a typical method to produce an optical vortex lattice (OVL). In this letter, via defining the wave vector space coordinate system, a modulating method of OVL with MPWI is proposed, the OVLs generated by four plane wave and five plane wave interference are simulated, the gradient force and energy flow of the OVL are calculated, and its application in the field of particle manipulation is analyzed. Accordingly, a more flexible and richer optical field distribution is obtained via adjusting the size of the partial wave vector and the angle of the rotation wave vector. Finally, by analyzing the gradient force and energy flow, it is found that the light field with a specific purpose can be generated by this method when manipulating particles. This study enriches the diversity of modes of OVL generated by MPWI and provides a novel idea for the study of OVL based on MPWI.
