Abstract:
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.
