APhotorefractive properties of liquid crystal hybrid thin film based on side polished fiber sensor

  • 摘要: 利用侧边抛磨光纤(SPF)传感器抛磨区对外界折射率敏感的特性,研究了混合有偶氮苯(AZO)和手征材料(ZLI811)的液晶混合物薄膜在紫外光照射下产生的光折变效应。将液晶、AZO和ZLI811等3种材料的混合物涂覆在经过标定的SPF传感器的抛磨区上,制备成混合物薄膜。用UV光照射光敏薄膜导致SPF中传输光功率改变。实验表明:混合物薄膜在UV光照射下有光敏特性,会产生折射率变化,其折射率从1.474变到1.470。这表明此光敏薄膜材料是负光折变材料。这种光敏薄膜材料可应用于制作新型全光纤光控器件和传感器。
