Bragg gratings based on hybrid polymers for analytical sensor technologies

用于分析传感器技术的基于混合聚合物的布拉格光栅

基本信息

项目摘要

The objective of this proposal is the development of an optical sensor system for the qualitative and quantitative analysis of liquids and gases. For this purpose, the photonic structure of a Bragg grating will be used as its feasibility in Ormocer® hybrid polymers has already been proven within the scope of the DFG-projects.The striven concept is based on an optical splitter system, which is molded into hybrid polymers via the innovative UV enhanced substrate conformal imprint lithography (UV-SCIL). This compact system of waveguides and couplers, covering only few square centimeters, comprises a matrix of volume type Bragg gratings with different periodicity. The gratings are induced by using static phase mask technology combined with a KrF-Excimerlaser. Introducing a broad banded incident spectrum of light into the sensor system, a polychromatic reflection is created as sum of the individual reflections of each inscribed Bragg grating. To compensate possible cross sensitivities (e.g. due to temperature fluctuations) individual Bragg gratings could be isolated. Further on, the targeted concept allows a selective sensitization of single elements aiming for a general or analyst specific increase in sensitivity. Due to the fact of using Bragg gratings as sensor elements, a singular connection of the sensor suffices, realized by the coupling of a single-mode fiber to the system. To characterize and improve the system integration, an analysis and optimization of several coupling strategies is striven within this project.
该提案的目标是开发用于液体和气体定性和定量分析的光学传感器系统。为此,布拉格光栅的光子结构将被用于Ormocer®混合聚合物中,其可行性已在DFG项目范围内得到证明。这一概念基于分光器系统,该系统通过创新的紫外增强衬底保形压印光刻(UV-SCIL)成型为混合聚合物。这种由波导和耦合器组成的紧凑型系统仅覆盖几平方厘米,包括具有不同周期性的体积型布拉格光栅矩阵。光栅是用静态相位掩模技术和KrF准分子激光诱导的。将宽带入射光谱引入传感器系统,产生多色反射,作为每个刻写布拉格光栅的单独反射的总和。为了补偿可能的交叉灵敏度(例如,由于温度波动),可以隔离单独的布拉格光栅。此外,靶向概念允许选择性敏化单一元素,旨在提高灵敏度的一般或分析师特定性。由于使用布拉格光栅作为传感器元件的事实,通过将单模光纤耦合到系统来实现传感器的单一连接就足够了。为了表征和改进系统集成,在该项目中努力分析和优化几种耦合策略。
