It can emit relatively high-power CW and pulsed waves with the output power reaching up to ­hundreds of mWs (Williams 2007). In general, QCLs are operated at low temperatures. The emission efficiency decreases with increasing temperatures (Indjin et al. 2003; Mátyás et al. 2010). This disadvantage has been addressed and resolved recently (Belkin et al. 2007). QCLs are made up of heterojunctions, which are junctions of lattice-matched semiconductors h ­ aving different band gaps. 5 and consists of an injector, an injection ­barrier, and an active region.

Reprinted from Huber, R. , Appl. Phys. ) SIS mixers offer the best sensitivities, closely approaching the quantum limit. A heterodyne detector has a complex structure than a direct detector, but it enables the measurement of the amplitude and phase information with higher sensitivity. This coherent detection method has 100 dB times higher signalto-noise ratio than direct detection. High-resolution heterodyne detection is an important technique in astronomy and atmospheric ­science (Kulesa 2011).
