✦ Synopsis

In this paper, we show experimentally that large photosensitivity in dye-Ε½ doped polymer optical fibers can be obtained with small pump power about . 1 mW at visible wavelength. The fiber has two identical cores each doped with fluorescein, and the pump beam is launched axially into one of the cores. However, when the pump beam at UV wavelength is launched into the fiber transversely, large photosensitivity is also observed. We also show that gratings can be written in polymer fiber and preform.

Improved understanding of the underlying fundamental mechanisms of the photosensitivity used to create index change within optical fibers can lead to substantial improvements in optimizing these changes for fiber grating writing. Recent work in unravelling and understanding photosensitization has le
