The phonon-assisted laser operation (4.2--77 /sup 0/K) of multiple quantum-well Al/sub x/Ga/sub 1-x/As-GaAs heterostructure diodes is described. Laser operation is observed on phonon sidebands approx.36 meV below the lowest confined-particle transitions. Tunnel injection into the confined-particle states, with light emission and negative-resistance regions, is also observed in these multiple quantum-well heterostructures. Two different multiple quantum-well heterostructures grown by metalorganic chemical vapor deposition are described. The first consists of six GaAs quantum wells (L/sub z/approx.120 A) coupled by five Al/sub x/Ga/sub 1-x/As (xapprox.0.3) layers (approx.120 A), and the second is similar except for a reduction in layer size to approx.50 A.
