ULTRAVIOLET LIGHT EMITTING DEVICES HAVING ENHANCED LIGHT EXTRACTION

摘要

Light emitting devices having an enhanced degree of polarization, PD, and methods for fabricating such devices are described. A light emitting device may include a light emitting region that is configured to emit light having a central wavelength, λ, and a degree of polarization, PD, where PD>0.006λ−b for 200 nm≦̸λ≦̸400 nm, wherein b≦̸1.5.
