ABSTRACT:
In an optical modulator, an electro-optic crystal is used. A pyroelectric body is connected to the electro-optic crystal through electrical interconnections. A polarizer and an analyzer are respectively arranged in spaced relation to an input side and an output side of the electro-optic crystal. The pyroelectric body receives heat generated by any of light, laser light, an electric resistor or heat generated from absorption of an electromagnetic wave or a radioactive ray. When heat energy is applied to the pyroelectric body, charges are produced in the pyroelectric body, so that a voltage based on the charges is applied to the electro-optic crystal. In this way, a plane of polarization in the electro-optic crystal is rotated so that the amount of light passing through the analyzer is varied in accordance with an applied heat energy.
