High-Power Quantum-Cascade Lasers Emitting in the 8-μm Wavelength Range

Molecular beam epitaxy techniques were used to grow a quantum-cascade laser (QCL) heterostructure based on an In 0.53 Ga 0.47 As/Al 0.48 In 0.52 As heteropair lattice-matched with an InP substrate. InP layers were used to form an optical waveguide. The obtained QCL heterostructure ensured room-tempe...

Zusammenfassung:	Molecular beam epitaxy techniques were used to grow a quantum-cascade laser (QCL) heterostructure based on an In 0.53 Ga 0.47 As/Al 0.48 In 0.52 As heteropair lattice-matched with an InP substrate. InP layers were used to form an optical waveguide. The obtained QCL heterostructure ensured room-temperature lasing in the 8-μm wavelength range at a maximum output optical power of 0.45 W from one facet in a standard ridge geometry of the Fabry–Pérot cavities formed by cleaved facets.
