This proposal is focused on the development of novel silica optical fibres which have enhanced Rayleigh scatter by post processing using the fibre's photosensitive response with UV light on the fibre pulling tower during the manufacture. We have shown very recently that UV exposure of an optical fibre dramatically increases the Rayleigh scatter by x100, which allows high sensitivity sensing temperature, strain or pressure with a high signal-to-noise ratio. This technique will enable high scatter optical fibre (ISOF) to be manufactured and protected with a polymer coating after post processing, ready for immediate use. Connected to this theme is the development of novel elastomeric photosensitive polymers, poly-dimethyl-siloxane (PDMS) based on the basic ingredient of the silica fibre -SiO2. The polymer will be synthesized to enhance its photosensitivity without compromising its mechanical properties, so that its elastomeric properties will be retained. 3D printing techniques will be developed to directly print complex structures and optical fibres for use with LED lighting and biomedical applications, e.g. in lab-on-a-chip.These two innovations of enhanced Rayleigh scatter and 3D printable stable photosensitive elastomers will greatly enhance the competitiveness of Canada in the world.

该提案的重点是开发新型石英光纤，该光纤在制造过程中利用光纤对光纤拉拔塔上的紫外光的光敏响应进行后处理，从而增强了瑞利散射。最近我们已经证明，光纤的紫外线照射可将瑞利散射显着增加 100 倍，从而可以以高信噪比实现高灵敏度感测温度、应变或压力。该技术将能够制造高散射光纤（ISOF），并在后处理后用聚合物涂层进行保护，以便立即使用。 与这一主题相关的是新型弹性体光敏聚合物的开发，即基于二氧化硅纤维基本成分 - SiO2 的聚二甲基硅氧烷 (PDMS)。该聚合物的合成将增强其光敏性，同时不影响其机械性能，从而保留其弹性性能。将开发 3D 打印技术来直接打印复杂结构和光纤，用于 LED 照明和生物医学应用，例如：增强瑞利散射和3D打印稳定光敏弹性体这两项创新将大大增强加拿大在世界上的竞争力。
