Abstract :
Continuous-wave operating singlemode quantum-cascade lasers with a threshold current of 75 mA and total power consumption of less than 2 W are presented. The lasers are grown by metal-organic vapour- phase epitaxy; they function up to temperatures higher than 50degC and the emission wavelength is 5.25 mum.
