Spectroscopic Characterization of Plastic Optical Fibers Doped With Fluorene Oligomers

The optical properties of four fluorene oligomers embedded in plastic optical fiber have been investigated by using steady-state luminescence technique. In particular, we study the dependence of the optical spectra with dopant oligofluorene, emission wavelength, excitation wavelength, and light propagation distance through the fiber. Using this information, we have characterized the optical loss in these doped optical fibers.
