摘　　要：对熊猫保偏光纤热极化 ,制成了一种新型保偏光纤电光相位调制器。在 2 80℃温度下 ,在磨抛并镀有微带电极的熊猫光纤两侧加 30 0 0V直流高电压进行极化 ,制成的电光相位调制器的电光系数为 0 47± 0 .0 5pm/V。此新型光纤电光相位调制器由保偏光纤制成 ,可用其构成偏振稳定的干涉型全光纤器件。A novel fiber electro-optic phase modulator has been fabricated with the thermal poling of polarization maintaining fiber. A PANDA polarization maintaining fiber polished and deposited with micro-strip electrode was poled as applied DC 3000 V voltage on its both sides at temperature 280°C. The electro-optic coefficient of the electro-optic phase modulator is 0.47 ±0.05 pm/V. Because built from polarization maintaining fiber, the phase modulator may be used in all fiber device based on fiber interferometer with polarization stability.
