Abstract (en)

[origin: CN101461069A] Disclosed is a multiple quantum-well structure (1), which comprises at least a first quantum-well structure (2a) for generating radiation of a first wavelength (6) and at least a second quantum-well structure (2b) for generating radiation of a second wavelength (7) that is greater than the first wavelength (6), and which is intended for emission of radiation of a primary wavelength (14), wherein the second wavelength (7) differs from the first wavelength (6) in such a way that the primary wavelength (14) changes only by a specified maximum value on occurrence of a shift in the first wavelength (6) and the second wavelength (7). Additionally, a radiation-emitting semiconductor base and a radiation-emitting component are disclosed.
