摘要： A terahertz-wave element includes a waveguide (2, 4, 5) that includes an electro-optic crystal and allows light to propagate therethrough, and a coupling member (7) that causes a terahertz wave to enter the waveguide (2, 4, 5). The propagation state of the light propagating through the waveguide (2, 4, 5) changes as the terahertz wave enters the waveguide (2, 4, 5) via the coupling member (7).

摘要： The invention relates to an oscillator for generating a wave including a terahertz-order frequency from the beat of two optical waves generated by a dual-frequency optical source (10). The oscillator comprises: a modulator (12) having a non-linear transfer function for generating harmonics at a frequency lower than one terahertz for each of the optical waves generated by the dual-frequency optical source; an optical sensor (14) capable of detecting at least one harmonic for each of the optical waves generated by the dual-frequency optical source, and of converting the detected harmonics into an electric signal; a comparator (15) for comparing the electric signal to a setpoint electric signal; and control means (16) for controlling at least one member of the dual-frequency optical source from a signal obtained from the signal resulting from the comparison.

摘要： A terahertz-wave generating element includes a waveguide including an electro-optic crystal; an optical coupling member that extracts a terahertz wave, which is generated from the electro-optic crystal as a result of light propagating through the waveguide, to a space; and at least two electrodes that cause a first-order electro-optic effect in the electro-optic crystal by applying an electric field to the waveguide so as to change a propagation state of the light propagating through the waveguide. A crystal axis of the electro-optic crystal of the waveguide is set such that the terahertz wave generated by a second-order nonlinear optical process and the light propagating through the waveguide are phase-matched.
