聚合物敷层光纤相位调制器

Phase Modulator of Optical Fiber with Organic Copolymer

利用有机聚合物（ＶＤＦ／ＴＥＦ）敷层光纤制备了一种光纤相位调制器，它具有宽带特性（１ＫＨｚ一６０ＭＨｚ）和一定的相移灵敏度（低频区为３．５×１０￣（－２）ｒａｄ／ｖ／ｍ，高频区为５．０×１０￣（－２）ｒａｄ／ｖ／ｍ）．采用独特的镀敷和整形工艺，平滑了频率响应曲线，增加了带宽的利用率。

ll-fiber phase modulator was manufactured using the organic copolymer coating.The performance of this modulator was demonstrated over a wide frequency range, from 1KHz to60MHz,A phase shift of 3. 5× 10￣(-2) rad/V/m was measured in the low frequency region,5.0×10￣(-2) rad/V/m in the highfrequency region,In order to make good use of the frequency band thefrequency responce curve was smoothed utilizing the coat and rectifying technology.
