  • Abstract
    Surface-plasmon distributed-feedback quantum cascade lasers with a first-order grating realised by the sole patterning of the top metallic contact are demonstrated. The devices have a single-mode emission with a sidemode suppression ratio greater than 20 dB. The emission wavelength at 78 K is centred at 7.3 m and has a tuning rate as a function of temperature 0.4 nm/K.
