Abstract

We explore phase and polarization singularity characteristics including the formation spiral and saddle pattern around V-singularity, due to propagation of converging-diverging beam of light through a tilted-rotated quartz half-waveplate. Such a system modifies the output beam characteristics significantly via coupled linear-circular birefringence experienced by a beam of light due to shape of the path – wave vector dependent Pancharatnam-Berry type geometric phase. Topological characteristics of the output beam for different input beam and waveplate orientation conditions are characterized using spatially-resolved Stokes parameter and weak measurement methods. Understanding the formation and manipulation of topologically structured optical beam using a single piece of optical component can pave the way to its widespread application.
