摘要：

We have developed a 1.3 mu m phase-shifted dual-mode laser diode (pDML) for a tunable continuous-wave terahertz (CW THz) emitter. The mode beat frequency of the pDML is continuously tuned from 250 to 1480 GHz by introducing monolithically integrated micro-heaters and multiple sections to an all-active structure. The pDML shows a narrow spectral linewidth and a strong four-wave mixing signal throughout the entire tuning range. By combining InGaAs based photomixers, we have successfully generated continuous-wave THz radiation, and confirmed the precise beat frequency settings and fast sweeping of this. This pDML operating at 1.3 mu m shows excellent performance in terms of THz conversion efficiency, tuning range and thermal stability.
