Title: OPTICAL MODULATION ELEMENT AND ELECTRIC FIELD SENSOR
Abstract:
[Problem] To obtain an optical modulation element which is capable of modulating laser light L incident thereon by means of a compound semiconductor single crystal that has properties of producing an electro-optic effect, and wherein attenuation of signal intensity in a low frequency band is prevented without lowering the carrier concentration in the compound semiconductor. [Solution] An optical modulation element 23 is provided with: an incidence limiting means 25 which is provided on or in the vicinity of an incident surface 24a of a compound semiconductor single crystal 24, on said incident surface 24a laser light L being able to be incident, and which prevents light other than the laser light L from being incident on the incident surface 24a; and a shielding material 26 which is formed from a material having light shielding properties and low dielectric constant, and which covers a surface 24c of the compound semiconductor single crystal 24, said surface 24c extending along the traveling direction of the laser light L incident on the compound semiconductor single crystal 24.
