报道了一种基于三阱有源模块的太赫兹量子级联激光器的设计。每个模块由两个用于两种激光状态的隧道耦合阱和另一个用于共振声子消居和载流子注入的阱组成。这种设计是目前已发表的各种工作装置中最简单的。测试装置的激光频率为3.4太赫兹，最高工作温度为142 K。(c) 2007年美国物理学会。
The authors report on a design of terahertz quantum-cascade lasers based on three-well active modules. Each module consists of two tunnel-coupled wells for the two lasing states and another well for both resonant-phonon depopulation and carrier injection. This design is the simplest so far among the various published working devices. The test device has a lasing frequency of 3.4 THz and maximum operating temperature of 142 K.
