Abstract :
The electro-optical modulator based on Pockels effect implements the transition from electrical signal to optical signal. This makes using optical fiber in EMC measurements come true. This paper describes the principle of modulators based on Pockels effect, designs the modulator with high precision, calculates the electric field in the modulator, discusses the parameters of the modulator, and gives the equivalent electrical circuit.
