We found that additional RTA at around 750 C greatly increases the photoluminescence (PL) intensity of solid-source MBE grown GaInNAs, while a relatively low in-situ annealing temperature, i.e., growth temperature for the p-Al0.3Ga0.7As cladding layer, at around 600 C is enough to improve the crystallinity of GaInNAs if additional RTA is performed. Consequently, a 10-Gb/s operation of a GaInNAs edge-emitting laser was achieved above 70 C
