Continuous wave terahertz quantum cascade laser

Continuous wave terahertz quantum cascade laser

Reports 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 4 K with a threshold current of 160 mA, and an output power of /spl sim/25 /spl mu/W. In pulsed mode the maximum operati...

Zusammenfassung:Reports 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 4 K with a threshold current of 160 mA, and an output power of /spl sim/25 /spl mu/W. In pulsed mode the maximum operating temperature is 52 K with a threshold current of 108 mA at 4 K.
