Abstract

In this paper, we shall briefly review some recent works done at the Pennsylvania State University on the photorefractive (PR) fibers and their applications. Firstly, a laser heated pedestal growth (LHPG) technique to grow single crystal PR fiber is briefly described. A technique of constructing phase conjugate PR fiber hologram is introduced. Angular and wavelength selectivities for the fiber holograms are evaluated, in which we have shown that the reflection-type wavelength-multiplexed fiber hologram offers a uniform and higher selectivity, as in contrast with the transmission-type. Cross-talk noise for reflection-type wavelength-multiplexed fiber hologram is also calculated, in which we have shown that the noise level would be lower by using a narrower linewidth of the light source. An application of the PR fiber hologram to optical interconnection is advocated, for which a 5-dimensional holographic memory is addressed. Finally, a simple experimental demonstration using a Ce:Fe: doped LiNb0₃ PR fiber with a tunable visible-light diode laser is given, in which we have expressed that the potential application to large capacity holographic memory, reconfigurable interconnects, and many others are possible.
