Notes:
We have clearly demonstrated a single spot in a far-field pattern of nitride-based laser diodes with a thick n-AlGaN layer/low-temperature-deposited buffer layer/sapphire. This AlGaN-based structure has realized a crack-free 1-μm-thick n-type Al0.06Ga0.94N cladding layer, leading to suppression of optical leakage from the waveguide region to the underlying layer and improvement of optical confinement. The threshold current of the laser diode is about 230 mA, which is comparable to or better than that of our laser diodes with the conventional GaN-based structure. © 1999 American Institute of Physics.
