Ultraviolet light emitting devices having enhanced light extraction

摘要

Light emitting devices having an enhanced degree of polarization, P D , and methods for fabricating such devices are described. A light emitting device may include a light emitting region (1005) that is configured to emit light having a central wavelength, », and a degree of polarization, P D , where P D > 0.006 » - b for 200 nm ‰¤ » ‰¤ 400 nm , wherein b ‰¤ 1.5.
