Abstract

The midinfrared emission from electroluminescent devices with quantum cascade (QC) active regions based on InGsAs/InP heterostructures was studied. The realization of InP-based QC lasers with aluminum-free waveguides was also discussed. A highly doped (n=10 18 cm -3) GaInAs contact layer was grown on top of an active core. A fourier transform infrared (FTIR) spectrometer equipped with a liquid N 2 cooled HgCdTe detector was used for the spectral measurements.
