WebTerahertz quantum cascade lasers QCLs are an emer-gent compact source of narrowband terahertz radiation in the wavelength range of 60–350 m 5–0.85 THz .1 In order to achieve lasing, the laser mode requires strong confinement within the active region. This challenge is addressed by the use of surface plasmon waveguides, of which two types have WebThe spectra are shifted for clarity. Several longitudinal modes of the Fabry-Pérot laser cavity separated by 28 GHz appear. Only the four strongest modes are labeled with their frequency. The frequency coverage is approximately 250 GHz. - "A compact, continuous-wave terahertz source based on a quantum-cascade laser and a miniature cryocooler."
