Current injection Ga/sub 0.47/In/sub 0.53/As/InP multiquantum well heterostructure lasers operating at 1.53 ..mu..m have been successfully prepared by molecular beam epitaxy. These lasers consist of four approx.70 A Ga/sub 0.47/In/sub 0.53/As wells and three approx.150 A InP barriers. The threshold current density is 2.7 kA/cm/sup 2/. In the temperature range of 10--75 /sup 0/C, the threshold-temperature dependence can be described closely by a single temperature dependence coefficient T/sub 0/. The measured T/sub 0/ is 45 K. No significant improvement in T/sub 0/ is observed in these multiquantum well lasers over conventional double-heterostructure lasers operating also at 1.5 ..mu..m.
