  • Publication number: 20240019473
    Abstract: A light sensor probe includes an optical sensor unit configured to modulate an incident light depending on an intensity of an electric field of a place on which the optical sensor unit is located and output the modulated light. The optical sensor unit includes an optical modulator having a modulation electrode integrally formed with antennas. The optical modulator is a branch interference type optical modulator and a reflection type optical modulator. An input optical fiber and an output optical fiber are formed by one input/output optical fiber. A package is formed by a metal plate which functions as a shielding layer to the electric field. An opening is provided on a tip surface at a position capable of being approached to a measurement place. An insulating layer is provided on an outermost surface of a circumference of the opening.
