Linearly polarized light from InGaN green light emitting diode grown on (0001) oriented sapphire is demonstrated by using sub-wavelength metallic nano-gratings. Polarization ratio can reach 7:1 (~88%), the highest ever reported from a single light emitting device. The polarization characteristics are studied and discussed in details
