| Abstract | Midinfrared emission from intersubband superluminescent light-emitting diodes is reported. We have obtained broadband emission spectra at around 7μm with a full width at half maximum of ∼2μm, using quantum-cascade-laser active regions designed to emit at 11 different wavelengths simultaneously. By introducing additional mirror loss in the Fabry–Perot resonator using just a single cleaved facet, with the other mirror formed by wet etching, the laser threshold current is significantly increased and superlinear light-current characteristics are observed. Optical peak powers of several tens of μW are measured at low temperatures. |
