THz-wave Pulse Frequency-Amplitude Modulation Enabled by Single Wavelength-Tunable Laser

Based on our devising THz-wave-generation method by photomixing using single wavelength-tunable laser, we design a pulse frequency modulation system. Experimental results show the feasibility of pulsed THz wave generation with different frequencies. Together with the use of a wavelength selective switch, the system can be developed into pulse frequency-amplitude modulation.
