Abstract

This paper provides a detailed analysis of electric field sensing using a slab-coupled optical fiber sensor (SCOS). This analysis explains that the best material for the slab waveguide is an inorganic material because of the low RF permittivity combined with the high electro-optic coefficient. The paper also describes the fabrication and testing of a SCOS using an AJL chromophore in amorphous polycarbonate. The high uniform polymer slab waveguide is fabricated using a hot embossing process to create a slab with a thickness of 50 μm. The fabricated polymer SCOS was characterized to have a resonance slope of ΔP/Δλ=6.83E5 W/m and a resonance shift of Δλ/E=1.47E-16 m(2)/V.

摘要

本文对使用平板耦合光纤传感器（SCOS）进行电场传感进行了详细分析。该分析表明，平板波导的最佳材料是无机材料，因为其具有低射频介电常数和高电光系数。本文还描述了使用非晶聚碳酸酯中的AJL发色团制造和测试SCOS的过程。使用热压印工艺制造出厚度为50μm的高均匀聚合物平板波导薄板。所制造的聚合物SCOS的特征在于共振斜率为ΔP/Δλ = 6.83E5 W/m，共振位移为Δλ/E = 1.47E-16 m(2)/V。
