TERAHERTZ technology is a fast growing field with applications in biology and medicine [1]–[4], imaging [5], [6], material spectroscopy and sensing [7]–[11], security [12]–[15], monitoring and spectroscopy in pharmaceutical industry [16], [17], and high-data-rate short-range communications [18]–[20]. Photomixers are promising continuous-wave terahertz sources as potentially compact, low-power-consuming, coherent, low-cost, and tunable sources [21]–[28]. A terahertz photomixer is a heterodyne scheme, in which output of two single-mode lasers or output modes of a dual-mode laser with their frequency difference falling in the terahertz range mix in a nonlinear medium, such as a photoconductor [27], [29] or a superconductor [30], and generate a signal, whose frequency is equal to the frequency difference of the two lasers or two modes of the dual-mode laser. The frequency of the generated terahertz signal can be tuned by tuning the central frequency of the lasers.
