Abstract
The difficulty of controlling the polarization of lager aperture VCSEL is the complicated transverse modes after analysing the structures of rectangle aperture VCSEL and sub-wavelength metal-grating VCSEL. So we put forward a new type of structure-oxidation type grating VCSEL structure. This structure can not only introduce anisotropy gain into active region but its biggest advantage is able to perfect control of large aperture VCSEL transverse mode. The sturcture was simulited by finite element software, and it is found that the structure achieve two goals when the grating ridge is 1.8 μm.
