Understanding polarization with gratings tilted to crystal axes: towards circularly-polarized VCSELs
We demonstrate that tailored anisotropies in VCSELs give rise to eUipticaΠy-polarized light. This can be achieved exploiting the intrinsic electro-optic anisotropy and a tilted surface grating with respect to crystallographic axes, targeting circular polarization with conventional grating-VCSEL technology.
