We report the first successful preparation of current injection GaInAsP/InP double heterostructure lasers operating at 1.3 ..mu..m by molecular beam epitaxy. The median threshold current density J/sub th/ is 3.5 kA/cm/sup 2/, while the lowest J/sub th/ is 1.8 kA/cm/sup 2/ for broad-area Fabry--Perot diodes of 380 x 200 ..mu..m and an active layer thickness of 0.2 ..mu..m. The threshold current-temperature dependence is described very closely by exp (T/T/sub 0/) with T/sub 0/ of 70--87 K in the temperature range 10/sup 0/--65 /sup 0/C. Elemental As and P (red phosphorus) were used as the primary molecular beam sources for deriving the As/sub 2/ and P/sub 2/ beams. In addition, the As and P ovens were equipped with recharge interlock systems. As a result, the growth chamber was always maintained in ultrahigh vacuum condition even during As and P recharge.
