Surface Emitting Quantum-Cascade Ring Laser

Quantum-cascade lasers with surface emission of radiation by means of a grating formed in the upper waveguide cladding layers by ion-beam milling are fabricated and studied. The active region of the laser heterostructure is based on the In 0.53 Ga 0.47 As/Al 0.48 In 0.52 As alloy alloys and uses a d...

Description
Summary:Quantum-cascade lasers with surface emission of radiation by means of a grating formed in the upper waveguide cladding layers by ion-beam milling are fabricated and studied. The active region of the laser heterostructure is based on the In 0.53 Ga 0.47 As/Al 0.48 In 0.52 As alloy alloys and uses a design with two-phonon resonance emptying of the lower level in the cascade. Room-temperature lasing near 7.9 μm is demonstrated for a laser with a ring-cavity diameter of 191 μm. The mode spacing in the lasing spectra corresponds to whispering-gallery modes.
