For safety reasons an arsine generator system (ASGS), operating on demand, was used instead of arsine cylinders as the source for MOCVD. Excellent compensated strained multiquantum well (S-MQW) laser devices were realised for the first time with this generator. The threshold current density for infinite cavity length is 84 A/cm2 per well. This value is among the best values reported for this type of structure
