Multi-Physics Modeling and Simulation of Electro-Optical Sensing

Abstract:

With the rapid development of UHV technology, Electric field measurement technique has attracted lots of people's attention.Electro-optical sensors for measuring the electric field to become the main method due to the crystal optical fiber preparation and mature technology. This article describes the basic principles that Mach - Zehnder of lithium niobate optical modulator for electric field measurements.Designing the Mach - Zehnder electro-optic sensors in the Comsol Multiphysics oftware, the calculation model for the simulation results of bending radius that the optical waveguide transmission power loss minimum, a 3dB directional coupler to determine the length of the arm and finally adding a signal voltage, the applied voltage is obtained a linear relationship between the output power.
