Abstract
Quantum Cascade Lasers (QCL), emitting between 5 and 9 μm, have been realised with a view to achieving QCLs fabrication on a production scale. The growth of the structures was carried out in a multi-wafer RIBER 49 system (13 x 2" platen), and the processing sequence involved an Inductively Coupled Plasma (ICP) step for homogeneity and reproducibility purposes. To validate the approach used, a first batch of lasers, emitting around 9μm, based on a design already published [1], has been realised. State of the art performance on these devices (Jth = 4.2 kA cm-2, η = 304 mW A-1, Pmax = 690 mW) has been achieved. A second set of strained balanced structures, emitting around 5.4μm, has been demonstrated, working in pulsed operation at room temperature(Jth = 3.9 kA cm-2, η = 362 mW A-1, Pmax = 420 mW).
