By means of computer-controlled liquid-phase epitaxy, multiple-quantum-well InP-In/sub 1-x/Ga/sub x/P/sub 1-z/As/sub z/ (xapprox.0.13, zapprox.0.29) heterostructures of uniform well (L/sub z/approx.160 A) and coupling barrier size are grown and are examined in photoluminescence. Laser operation (77 /sup 0/K) of a six-well five-barrier undoped quaternary quantum-well heterostructure is identified an LO phonon energy (1 x h..omega../sub LO/approx.30 meV) below the lowest confined-particle transitions (No. 1 e..-->..hh, E/sub 1/) or at energy h..omega..approx.E/sub 1/-h..omega../sub LO/.
