The polarity is a special property for III-nitride materials with wurtzite structure along different orientations. The influence of normal and reversed polarizations on laser performance of the violet laser diodes with Ga-face and N-face configurations is studied numerically. Specifically, the laser performance, band diagram, carrier confinement, and emission wavelength are investigated. The results show that the threshold current is improved and emission wavelength is redshifted when the laser diode is with reversed polarization.
