TERAHERTZ-WAVE GENERATING ELEMENT, TERAHERTZ-WAVE DETECTING ELEMENT, AND TERAHERTZ TIME-DOMAIN SPECTROSCOPY DEVICE |
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. |
