1. A frequency tunable terahertz continuous wave generator comprising:

  • an optical signal generator that generates a double-sideband optical signal by modulating an optical signal with a single wavelength output from a single light source in a Double-sideband-Suppressed Carrier (DSB-SC) scheme, feeds back and modulates the double-sideband signal n times (where n is an integer of at least

         1) in the DSB-SC scheme, and generates two optical signals with different wavelengths by selectively removing an unnecessary optical signal from among multiple double-sideband optical signals generated by feeding back the double-sideband optical signal; and

    an optical signal converter that performs conversion into a terahertz continuous wave by photomixing the two optical signals with the different wavelengths generated by the optical signal generator.
