Abstract
Mid-infrared semiconductor optical amplifier based on a quantum cascade active region, was presented. The oscillator was a 16 μm wide, 2mm long ridge waveguide where the single mode laser action was achieved by wet-etching a first-order Bragg grating. The laser was used to attain high output powers from distributed feedback quantum cascade lasers, without affecting their single mode behavior. High power single mode emission at λ ≈ 7.5 μm was achieved.
