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.

Abstract
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.File in questo prodotto:
