摘要: We report the first successful preparation of current injection GaInAsP/InP double heterostructure lasers operating at 1.3 μm by molecular beam epitaxy. The median threshold density Jth is 3.5 kA/cm2, while lowest 1.8 kA/cm2 for broad‐area Fabry–Perot diodes 380×200 and an active layer thickness 0.2 μm. current‐temperature dependence described very closely exp (T/T0) with T0 70–87 K in temperature range 10°–65 °C. Elemental As P (red phosphorus) were used as primary sources deriving As2 P2 beams. In addition, ovens equipped recharge interlock systems. a result, growth chamber was always maintained ultrahigh vacuum condition even during recharge.
