Abstract: The characteristics of a two-dimensional plasmon amplified in an active medium based on a terahertz quantum-cascade structure are calculated. It is shown that, for realistic parameters of GaAs/AlGaAs quantum-well structures (mobility of 2 $\times$ 10$^5$ cm$^2$ V$^{-1}$ s$^{-1}$ for an electron concentration of 5 $\times$ 10$^{11}$ cm$^{-2}$ and temperatures up to 77 K), the gain experienced by two-dimensional plasmons can be as high as 1500 cm$^{-1}$ at a frequency of 2.3 THz. Furthermore, due to strong localization of the plasmon electric field near a quantum well, a quantum-cascade active region with only a few periods is sufficient for amplification.
Keywords: plasmon, quantum-cascade laser, terahertz frequency range, quantum well.
