We have fabricated low-threshold, high-quantum-efficiency, room-temperature AlGaAs-GaAs double-heterojunction injection lasers from epitaxial structures grown by metalorganic chemical vapor deposition directly on Si substrates. These devices have broad-area (125 ..mu..m x 250 ..mu..m) pulsed threshold current densities as low as J/sub th/ = 3.5 kA/cm/sup 2/ at --23 /sup 0/C. Ridge-waveguide stripe-geometry lasers (5 ..mu..m x 250 ..mu..m) have pulsed threshold currents as low as 130 mA at --23 /sup 0/C. These stripe-geometry lasers have total external differential quantum efficiencies as high as eta/sub ext/ --70%, a value equal to the eta/sub ext/ measured for similar double-heterostructure lasers grown on GaAs substrates. These are the lowest threshold currents and highest external quantum efficiencies yet reported for lasers grown on Si substrates.
