The broader/commercial impact of this Small Business Innovation Research (SBIR) Phase II project is to advance the development of germicidal optical fibers (GOFs). GOFs are the first fiber technology that can effectively distribute ultraviolet (UV)-C radiation in pipes, tubes, and channels by side-emitting UV-C radiation along their entire length, like a glowstick. Placing these fibers in conduits found in hospitals, homes, and businesses can reduce infections, deaths, and operational issues caused by bacteria build-up. By expanding the use of the GOFs, the team hopes to can reduce reliance on toxic chemicals for disinfection and decrease harmful disinfection by-products. This research will increase the knowledge on the ability to manufacture specialty optical fibers as well as increase general knowledge on UV disinfection technologies. This SBIR Phase II project aims to address the logarithmic decay of light that occurs in all existing optical fibers. This limits the working length of GOFs. Technical improvements to the GOFs are needed to increase the uniformity of the light profile. Current draw tower manufacturing methods and equipment are not able to optimize the light profile. Therefore, the specific objectives of this project are to: i) modify the manufacturing equipment in a draw tower and ii) alter the optical configuration to increase the total light availability in the fiber. These objectives will increase the uniformity of light scattering along the length of the fiber and increase the length of GOFs that can be used in disinfection applications.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个小企业创新研究（SBIR）第二阶段项目的更广泛/商业影响是推动杀菌光纤（GOFs）的发展。GOFs是第一种可以像荧光棒一样沿管道、管道和通道沿其整个长度侧面发射UV-C辐射的光纤技术。在医院、家庭和企业的管道中放置这些纤维可以减少感染、死亡和由细菌积聚引起的操作问题。通过扩大GOFs的使用，该团队希望能够减少对有毒化学物质的依赖，并减少有害的消毒副产物。这项研究将增加对制造特种光纤的能力的知识，以及增加对紫外线消毒技术的一般知识。SBIR二期项目旨在解决所有现有光纤中发生的光的对数衰减问题。这限制了GOFs的工作长度。需要对gof进行技术改进，以增加光剖面的均匀性。目前的抽油塔制造方法和设备还不能优化抽油塔的光形。因此，该项目的具体目标是：i)修改拉拔塔中的制造设备；ii)改变光学配置，以增加光纤中的总光可用性。这些物镜将增加沿光纤长度的光散射均匀性，并增加可用于消毒应用的gof的长度。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
