  • Abstract
    A distributed feedback quantum cascade laser array emitting at lambda~10 mum is reported. Utilising a ridge width dependence on emission wavelength, the array of laser ridges exhibited a tuning range in excess of 230 nm over the temperature range of 140 to 380 K. Singlemode operation with sidemode suppression ratios of ges 25 dB and a combined tuning coefficient of -0.1 cm-1 K-1 are demonstrated.
