摘要：
Demonstration of a terahertz quantum cascade laser grown by a low-pressure metalorganic vapor phase epitaxy is reported. The structural analysis of the grown structure shows a very high degree of vertical uniformity and sharp interfaces. Lasing emission at lambda=90 mu m up to 93 K with a threshold current density J(th)=330 A/cm(2) at 7 K was obtained in a structure incorporating a single plasmon waveguide.
