摘要： A quantum cascade laser structure in accordance with the invention comprises a number of cascades (100), each of which comprises a number of alternately arranged quantum wells (110a to 110j) and barrier layers (105 to 105j). The material of at least one quantum well (110a to 110j) as well as the material of at least one barrier layer (105 to 105j) is under mechanical strain, with the respective strain being either a tensile strain or a compression strain. The quantum wells (110a to 110j) and barrier layers (105 to 105j) are engineered in the quantum cascade laser structure in accordance with the invention so that existing strains are largely compensated within a cascade (100). In the quantum cascade laser structure in accordance with the invention, each material of the quantum wells (110a to 110j) has only one constituent material and the material of at least one barrier layer (105d, 105e, 105f) has at least two constituent materials (111a, 111b, 112a, 112b, 113a, 113b).
摘要翻译：根据本发明的量子级联激光器结构包括多个级联（100），每个级联包括多个交替布置的量子阱（110a至110j）和阻挡层（105至105j）。至少一个量子阱（110a至110j）的材料以及至少一个阻挡层（105至105j）的材料处于机械应变下，其各自的应变是拉伸应变或压缩应变。根据本发明，量子阱（110a至110j）和势垒层（105至105j）被设计在量子级联激光器结构中，使得现有的应变在级联（100）内大量补偿。在根据本发明的量子级联激光器结构中，量子阱（110a至110j）的每种材料仅具有一种构成材料，并且至少一个阻挡层（105d，105e，105f）的材料具有至少两种构成材料（111a，111b，112a，112b，113a，113b）。

摘要： A quantum well structure according to the invention includes a quantum well layer (107) arranged between two barrier layers (109, 112). It is distinguished in that at least one of the barrier layers (109) includes nanostructures (110) which compensate or modulate a lateral homogeneity of the barrier layer (109), that exists without the nanostructures (110), that is to say a homogeneity in the directions extending perpendicularly to the stacking direction of the layers in the quantum well structure.
