Abstract :
We present arbitrary single-frequency continuous-wave (CW) terahertz (THz) generator based on photomixing of a scanned CW laser and a fixed CW laser, which are locked to two independent optical combs, respectively. Behavior of tight locking and continuous tuning of its output frequency is monitored at real time by a THz-comb-referenced spectrum analyzer.
