Generation of orthogonal lattice fields

摘要

Orthogonal polarization singularities have been introduced recently. Generation of orthogonal fields for V-points and C-points singularity entails the use of different combinations of optical elements. Some of the polarization singularity lattice fields generated by interference contain juxtaposed orthogonal C-points but not orthogonal V-points. In this paper, we present an interference method to generate orthogonal lattice fields in which each polarization singularity is replaced by its orthogonal state. Generation of new polarization singularity lattice fields by superposition of orthogonal and non-orthogonal lattice fields is discussed. (c) 2019 Optical Society of America.
