Abstract

According to the theory of electric-optical effects to design the slice pattern, size and the appropriate combination of chip, the γ₆₃-transversal electric-optical modulator (pockells box) of KDP crystal is designed in the article. The high semiwave voltage of KDP crystal (~8000V) will be decreased to several hundred voltages which can be used in practical application and the temperature stability of this electric-optical modulator is improved. The experimental result shows that the signal transfered by laser is not affected with the changing of the working temperature of this electric-optical modulato. While the He-Ne laser (λ=0.6328μm)is used to the communication, the semi-wave voltage will be reduced to 687.5V practically and the coefficient of eletric-optical is γ₆₃=11.98×10^-12m/V. It is consistent with the theoretical value.
