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。
A kind of optical fiber phase modulator was fabricated by using organic polymer (VDF / TEF) cladding optical fiber. It has wideband characteristics (1KHz-60MHz) and certain phase-shift sensitivity (3.5 × 10-2) rad / v / m for the high frequency region and 5.0 × 10 -2 (rad / v / m) for the high frequency region. Unique plating and shaping process, smoothing the frequency response curve, an increase of bandwidth utilization.
