摘要： First and second laser beams are incident on a difference frequency mixing unit, and the two laser beams overlap in the difference frequency mixing unit, thereby generating a terahertz wave whose frequency is a frequency difference between the two laser beams. Each laser beam has a spatial spread in a frequency gradient direction, and a spatial frequency distribution of each laser beam is a distribution in which a magnitude of a frequency gradually increases in the frequency gradient direction. A frequency difference between the two laser beams is equal in each position in an overlapping region of the two laser beams. A terahertz wave of a single frequency is generated from this overlapping region. By spatially shifting the first laser beam and the second laser beam with respect to each other in the frequency gradient direction, the frequency difference in the overlapping region is changed, which changes the single frequency.

摘要： Terahertz waves are generated by modulating the output of a cw laser to produce an optical signal with equally spaced frequency components. The modulated optical signal is supplied to a nonlinear optical waveguide in which it undergoes self-phase modulation, thereby producing at least two further frequency components that are separated by a desired frequency in the terahertz gap and have a sufficient magnitude. An optical filter selects the two frequency components, which are directed to a photomixer, that produces an electrical signal with the same frequency as the beat frequency. The photomixer is biased, and coupled to an antenna, so that the resulting electrical signal causes an electromagnetic wave having a frequency in the terahertz range to propagate from the antenna.
