【Abstract】 Abstract InGaAsP/InP strained layer quantum well (SL-QW) materials grown by low pressure metal organic chemical vapour deposition (LP-MOCVD) are reported. The telationship between the material parameters and the epitaxial conditions, the structural design of quantum well device and its applications are given in this paper. 1. 3μm SL-QW laser and 1. 55μm SL-QW lasers with broad area threshold current densities as low as 400A/cm2 and 600A/cm2(at cavity length 400pm), DC-PBH stripe device threshold current 7￣ 12mA and 9￣ 15mA were obtained, respectively. High power 1. 3μm QW light emitting diodes (LED), and InGaAs PIN photodetectors with high performace were also obtained by LP-MOCVD epitaxial materials.更多还原
