  • Abstract
    We report novel quantum cascade laser sources based on difference-frequency generation in nonlinear sections localized near exit facets. This new approach allows for infrared-to-terahertz conversion efficiencies above 1mW/W2. Experimentally, devices operating at 4THz are discussed.
