Paper Abstract

We have explored a new doping method, which could disperse densely dyes into polymers, and have developed the present method into preparation of polymeric devices, such as storage media, luminescent media, switching devices, and waveguides. Preparation of the waveguide was based on dispersal of organofluorine (OF) compounds with a low refractive index in a polymer plate functioning as a cladding layer. The layer dispersed with the OF compound showed uniform concentration of the OF compound independent of the dispersal depth indicating that dispersion behavior was not governed by Fick's law. This means that the waveguide in the present study is step index. As a further development, we expanded the present method to preparation of a polymeric optical amplifier (POA) because reduction in intensity of a signal beam is clear due to driving of splitters in a short distance network using polymer optical fibers with large cores. A laser dye was dispersed densely within the core by the present method, followed by the dispersal of the OF compound to form the cladding layer resulting in the fabrication of POA with the large core. Amplification of the signal beam at 650 nm was confirmed in the waveguide upon irradiation of a pulsed laser.
