The Magnetic Field

The magnetic-field dependence of the mid-infrared quantum-cascade laser emission spectra is used to identify the particular Wannier-Stark states responsible for the laser action in two different laser designs. The active regions in both QCLs are based on the bound-to-continuum design, but have differing degrees of coupling between the injector miniband and the bound state. The effects of the magnetic field and the injection-barrier width on the emission wavelength indicates that the laser emission in the QCL with less coupling between the injector and the bound state originates from a transition between the injector and extractor minibands. The transition from injector miniband to extractor miniband has both a lower energy and a lower oscillator strength than the transition originating from the bound state, but dominates because of the low population of the upper bound state. This result has important implications for further miniband engineering of QCL active regions for laser action at the shortest possible wavelengths. New quantum-cascade laser sample, designed regarding the high-magnetic-field spectroscopy results mentioned above, indeed operates at shorter wavelength and demonstrates outstanding performance up to room temperature.
