Paper Abstract

We propose a new method for one-way parallel data transmission through a multimode optical fiber. The method consists of 'recording process,' in which each hologram that corresponds to one pixel is recorded one by one in a photorefractive crystal BSO, and 'read out process,' in which some of the holograms are illuminated simultaneously by readout beams and the corresponding pixel images are transmitted in parallel through a multimode optical fiber. In our study, a reference beam is also transmitted by the other multimode optical fiber rather than a single mode optical fiber. Although modal dispersion distorts the wave front of the reference beam, the phase conjugated beam can read out the holograms precisely by tandem arrangement of two photorefractive crystals BSO and BaTiO3. We demonstrated experimentally a multipixel image transmission through a 5 m multimode optical fiber. The images could be transmitted more than 20 times for single recording process.
