Abstract [en]

We show that the use of a low growth rate combined with low N flux and RF power during molecular beam epitaxy (MBE) growth of dilute nitrides can efficiently enhance N incorporation while retaining good optical quality. A maximum light emission wavelength of 1.44 and 1.71 mu m has been obtained at 300 K from GaNAs and GaInNAs quantum wells, respectively. We demonstrate high-performance 1.3 pm GaInNAs multiple quantum well edge emitting lasers with record low threshold current densities, a 3 dB modulation bandwidth of 17 GHz at 300 K and capability of being modulated at 10 Gbit/s up to 110 degrees C without extra coolers. Our results show that MBE is an epitaxial technology suitable for the growth of dilute nitride materials and devices.
