Abstract
In the electric field measuring device, a DC bias circuit applying a DC bias voltage to an optical intensity modulator is disposed in an area, and a DC bias control portion controlling a DC bias voltage is disposed outside the area. An electrical signal of a DC bias voltage which is output from the DC bias control portion is converted into an optical signal by an electrical-optical converter (E/O) so as to be introduced into the area via an optical fiber, and the optical signal is converted into an electrical signal by an optical-electrical converter (O/E) disposed in the area such that the electrical signal is input to the DC bias circuit.
