Paper Abstract

High quality strained InAsP was grown using gas-source molecular-beam-epitaxy (GSMBE) and the band structure was determined. The conduction band discontinuity ratio of InAsP/InP heterostructure was about 0.35, contrary to the reported value of 0.75. We proposed a new InAsP/InAlGaAs material system with type-I superlattice suitable for a high performance LD for 1.3-micrometer optical subscriber systems. The crystal quality was improved by introducing an InP spacer layer and the RTA process. High characteristic temperature of 143 K was achieved with this material system.
