Abstract :
Summary from only given. We present a mid-IR semiconductor optical amplifier based on a quantum cascade (QC) active region, which has been used to attain high output powers from distributed-feedback (DFB) QC lasers without affecting their single mode behavior. The device was realized as schematically shown in a master oscillator-power amplifier (MOPA) configuration.
