ABSTRACT This proposal is to fund innovative exploratory research on producing polymer optical fibers with specified optical index profiles. By controlling the optical index profile, modal dispersion of the signal can be minimized and the speed of transmission can be increased from several Mbit/sec to the Gbit/sec range. The goal of the project is to develop a continuous drawing method that can be used to fabricate graded-index fibers efficiently. The Principal Investigator proposes to use photobleaching to control the optical index. As fibers are draw, oxygen or air is allowed to diffuse into them. The fibers is then irradiated by UV light. Because the concentration of oxygen at the outer region of the fiber is higher, photobleaching occurs at a higher rate, resulting in a spatially varying optical index. Experiments will be conducted to explore this concept of fabrication.

摘要 该提案旨在资助生产具有特定光学折射率分布的聚合物光纤的创新探索性研究。 通过控制光学折射率分布，信号的模式色散可以最小化，并且传输速度可以从几Mbit/sec增加到Gbit/sec范围。 该项目的目标是开发一种连续拉伸方法，可用于有效地制造梯度折射率光纤。 主要研究者建议使用光漂白来控制光学指数。 当纤维被拉伸时，允许氧气或空气扩散到其中。 然后用UV光照射纤维。 由于光纤外部区域的氧浓度较高，光漂白以较高的速率发生，导致空间变化的光学指数。 将进行实验来探索这种制造的概念。
