Abstract
The present invention relates to a gallium nitride nano superstructure and a preparation method thereof. The gallium nitride nano superstructure is used for realizing circularly polarized light output of the gallium nitride-based laser. The gallium nitride nano superstructure comprises, from bottom to top, a substrate, a dielectric film layer and a nano-grating structure layer, a grating material of the nano-grating structure layer comprising one of gallium nitride, N-type gallium nitride and P-type gallium nitride, a grating period being in a range of 100 nm-280 nm, a grating height being in a range of 100 nm-300 nm, and a grating line width being in a range of 50 nm-200 nm. The gallium nitride nano superstructure of the present invention can be applied to a gallium nitride-based laser to realize the circularly polarized light output of the gallium nitride-based laser.
