摘要： In a THz wave generator for generating a THz wave from a THz wave generating element by inputting a plurality of laser beams having different wavelengths to the THz wave generating element, all of the plurality of laser beams are formed into a pulse beam by the pulse generator and the pulse beam is amplified by a single optical amplifier E to which the laser beams are inputted with polarization planes of the laser beams being controlled, and then the pulse beam is inputted to the THz wave generating element F. Preferably, the plurality of laser beams having different wavelengths are generated by inputting single wavelength beam to a multi wavelength generator from single mode laser light source and by inputting light waves having a plurality of wavelengths generated from the multi wavelength generator to wavelength selecting means.

摘要： A light control element is provided with a thin board having electro-optical effects; an optical waveguide formed on the thin board; and a control electrode for controlling light that passes through the optical waveguide. The light control element performs speed matching between a microwave signal applied to the control electrode and the light, impedance matching of the microwaves, reduction of a driving voltage and high speed operation. In the control electrode of the light control element, a signal electrode and a grounding electrode are arranged on an upper side of the thin board, and on a lower side of the thin board, a second electrode including the grounding electrode is arranged. The second electrode is arranged not to exist below the signal electrode, especially for achieving impedance matching.

摘要： A light intensity attenuator and attenuating method is provided, by which a pulse-shaped optical surge can be attenuated and an optical signal component using desired light intensity can be output by using a simpler structural arrangement, and without using many optical components and circuits. In this method, an optical signal including a pulse-shaped optical surge component is received, and the optical signal is again output after the light intensity of the surge component is attenuated by a desired amount. Typically, (i) at least one of a substrate and an optical waveguide formed on the substrate is made of a material producing a nonlinear optical effect, and the refractive index of the optical waveguide with respect to the optical signal is smaller than the refractive index of the substrate with respect to a higher harmonic of the optical signal, thereby wavelength-converting a part of the input optical signal by the nonlinear optical effect into a light portion having a wavelength shorter than that of the optical signal, and scattering this converted portion, and (ii) a part of the optical signal is scattered by using a polar-molecule liquid including polar molecules.
