The optical polarization of AlN/AlxGa1-xN single quantum wells (x = 0.65) has been studied by means of photoluminescence (PL) spectroscopy. The predominant polarization component of the band-edge PL switched from E ∥ c to E ⊥ c at a well width around 2 nm. The emission intensity with polarization of E ⊥ c and the degree of polarization were found to decrease with increasing well width. The emission intensity with polarization of E ∥ c was found to increase with increasing well width.
