摘要：

Continuous Wave operation of Quantum Cascade Lasers (QCL) in the far-infrared emission is demonstrated for the first time. The devices designed using a three-quantum-well chirped-superlattice active region in a waveguide based on a single interface plasmon and a buried contact, with high reflectivity backfacet coating, results in continuous wave operation with optical output power of 250 mW at 10 Kelvin, at an emission wavelength of 66 mum. The lasers work continuously up to 30 Kelvin.
