Polarization Conversion in Uniaxial Crystals
When a linearly polarized beam is focused and then propagated through a uniaxial crystal, even when along the optic axis, complicated conversions may take place between different polarization components. Such an effect can be utilized for e.g. generation of optical vortices. Taking calcite crystal as an example, the conversion of polarization in uniaxial crystal is demonstrated in VirtualLab. The optical vortices generated within the process is visualized.
