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.

The computing device monitors the temperature of the PPLN crystal and corresponding power of the temperature control device during the changing, the temperature monitored using the temperature sensor. The computing device determines one or more of operating conditions of the temperature control device and an operating temperature of the PPLN crystal from a function of the power vs. the temperature.
