GaAs/AlGaAs Quantum Cascade Lasers

Quantum cascade lasers for the 10μm spectral region were fabricated. With the goal of miniaturization, improvement of device properties, and single mode emission, we have developed lasers with one-dimensional photonic crystals by deeply etched Bragg-mirrors. For the first time nearly lattice matched GaInNAs was successfully grown on GaAs substrates at 590°C, which allows an increase in the carrier confinement.
