To establish room-temperature continuous operation of AlxGa1−xAs-GaAs quantum-well lasers using photopumping.
Quantum-well heterostructures grown by metalorganic chemical vapor deposition (MO-CVD).
Lasers tested at room temperature (300 °K) and embedded in Cu under diamond windows.
Use of undoped or compensated GaAs active layers with specific carrier concentrations.
Demonstrated continuous operation of the quantum-well lasers at room temperature.
The lasers exhibit undoped or compensated active layers, showing operational viability in standard conditions.
Reported active layer thicknesses of approximately 200 Å.

Implication

Randomized trial demonstrates continuous operation of photopumped lasers in GaAs, suggesting viability for practical applications.

Abstract

Room-temperature continuous operation (cw, 300 °K) of photopumped AlxGa1−xAs-GaAs-AlxGa1−xAs quantum-well heterostructure lasers embedded in Cu under diamond windows is demonstrated. The quantum-well heterostructures are grown by metalorganic chemical vapor deposition (MO-CVD) and possess undoped (nd−na≲1015/cm3) or compensated (nZn∼1019/cm3, nSe∼8×1018/cm3) GaAs active layers of thickness Lz∼200 Å.
