This paper presents improvements to slab-coupled optical fiber sensors for electric-field sensing. The sensors are comprised of a potassium titanyl phosphate (KTP) crystal mounted on a D-fiber. The improvements are based on changing the crystal orientation, which enhances sensitivity due to a combined increase in the effective electro-optic coefficient and electric-field penetration into the KTP crystal. The paper provides a detailed comparison of the improved sensor, which uses x-cut KTP to the previous sensor design using z-cut KTP. The measurements show an 8.6× improvement in the sensitivity.
本文介绍了用于电场传感的平板耦合光纤传感器的改进。这些传感器由安装在D型光纤上的磷酸钛氧钾（KTP）晶体组成。改进基于改变晶体取向，由于有效电光系数和电场穿透KTP晶体的综合增加，从而提高了灵敏度。本文详细比较了使用x切割KTP的改进型传感器与之前使用z切割KTP的传感器设计。测量结果表明灵敏度提高了8.6倍。
