摘要
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.
