Broadly tunable single-mode mid-infrared quantum cascade lasers

“…On the short wavelength side, the problem with limited band offset of the conventional lattice-matched based material could be alleviated by using new material systems, e.g. strainbalanced InP-based [18,[136][137][138] or Sb-based material systems [139][140][141]. On the other hand, long wavelength midinfrared QCLs (8-12 μm) based on strain-balanced InP-based materials have also shown tremendous progress, taking advantage of the optimized active region and waveguide designs [142], demonstrating the great potential of achieving high performance QCLs in the longer wavelength range.…”

Quantum cascade lasers in chemical physics

“…Reaching wavelengths below 4 lm has proven to be very challenging [17,[43][44][45][46][47][48]. However this situation may soon change, as research in this field is active in several groups [45][46][47][49][50][51][52][53][54]. In the most widely used AlInAs/GaInAs material system, a short-wavelength mid-infrared QCL, emitting pulsed at 3.5 lm (at 280 K), was demonstrated using strain-compensated AlInAs/GaInAs on InP substrates [43].…”
