In this paper, we show experimentally that large photosensitivity in dye-ลฝ 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
