Data are presented showing that it is possible to photopump and operate a quantum well heterostructure laser at equivalent current densities (J/sub eq/) as low as 70 A/cm/sup 2/. Continuous 300-K laser operation of a single 60-A GaAs (x = 0) quantum well in the center of a approx.0.12-..mu..m-thick x'approx.0.30 Al/sub x/'Ga/sub 1-x/'As waveguide (and carrier reservoir), which is confined by x''approx.0.85 Al/sub x/''Ga/sub 1-x/''As layers, is demonstrated at I/sub eq/approx.0.4 mA (168 W/cm/sup 2/, J/sub eq/approx.70 A/cm/sup 2/). These quantum well heterostructures are grown by organometallic vapor phase epitaxy.
