摘要：
We report continuous wave operation of a 4.4 THz unipolar injection quantum cascade laser grown in the AlGaAs/GaAs materials system by molecular beam epitaxy. The device operates at 4K with a threshold current of 160 mA, and an output power of similar to 25 muW. In pulsed mode the maximum operating temperature is 52K with a threshold current of 108 mA at 4K.
