Holographic image storage in iron-doped lithium niobate fibers

Abstract

Holographic recording on a real-time basis of two-dimensional images in an iron-doped lithium niobate fiber with a 200 μm diameter and 3 mm length is demonstrated for the first time. The erasure time constant as a function of readout beam power, the diffraction efficiency as a function of incident reference angle, and the results of angular-multiple recording of two images are shown. These results suggest that the LN fiber could replace bulk materials for holographic recordings in optical parallel processing.

The Photorefractive Response of Zn and Mo Codoped LiNbO3 in the Visible Region

“…Volume holographic storage is a technology that can store information at high density inside a crystal, which exploits the "inside" of the storage material, rather than only using its surface, resulting in a massive increase in the capacity of the data storage. Lithium niobate (LN) crystal is an essential material in many applications [1][2][3][4][5], such as surface acoustic wave, waveguides, volume holographic storage, piezoelectric, pyroelectric, and integrated optics [6][7][8][9]. The performance of volume holographic storage is particularly prominent [10][11][12][13][14][15][16][17][18].…”

Photoluminescence properties of Nd: LiNbO3 co-doped with ZnO fiber single crystals grown by micro-pulling-down method

“…Among these materials, long-length and small-diameter bulk crystals are of considerable interest for high efficiency and miniaturization. In particular, fiber single crystals have already received attention as attractive materials for a variety of electro-optical applications [1][2][3] because of their extended interaction length and high optical intensity. LiNbO 3 is a widely studied optoelectronic material because of its technological applications.…”

The effect of the pressure difference across the free surface in case of a NdYAG micro fiber growth by the micro-pulling-down process

“…The near one-dimensional single crystal fibers have attracted some attention on the applications of optical and electronic devices [1][2][3]. There are several methods for growing fiber crystals [4].…”
