“…͓DOI: 10.1063/1.1380247͔ Photorefractive LiNbO 3 :Fe crystals have been of intense interest in the fields of holographic data storage [1][2][3][4] and narrow-band wavelength filters for optical telecommunications. [5][6][7][8] Photorefractive volume phase gratings can be produced in electro-optic materials by redistribution of excited carriers in the presence of light. One of the most important issues is the dark decay due to the dark conductivity.…”

The lifetimes of nonfixed holograms in LiNbO 3 :Fe crystals with doping levels of 0.05, 0.138, and 0.25 wt % Fe 2 O 3 have been measured in the temperature range from 30 to 180°C. The time constants of the dark decay of holograms stored in crystals with doping levels of 0.05 and 0.25 wt % Fe 2 O 3 obey an Arrhenius-type dependence on absolute temperature T, but yield two activation energies: 1.0 and 0.28 eV, respectively. For these crystals, two different dark decay mechanisms are prevailing, one of which is identified as proton compensation and the other is due to electron tunneling between sites of Fe 2ϩ and Fe 3ϩ . The dark decay of holograms stored in crystals with the doping level of 0.138 wt % Fe 2 O 3 is the result of a combination of both effects.

“…Thanks to its excellent selectivity, VHGs have become an ideal candidate for various promising technological applications such as neural networks, 7 optical correlators, 8 and holographic data storage. 9,10 VHGs also prove useful in telecommunications; essentially a one-dimensional photonic crystal when ⌬n is appreciable ͑⌬n Ն 10 Ϫ4 ͒, holographic gratings in the reflection geometry can serve as superior filters 11,12 for wavelength division multiplexing (WDM) thanks to their low cross talk and readily engineered bandwidths.…”

The finite dimension of the incident beam used to read out volume holographic gratings has interesting effects on their filtering properties. As the readout beam gets narrower, there is more deviation from the ideal response predicted for monochromatic plane waves. In this paper we experimentally explore beam-width-dependent phenomena such as wavelength selectivities, angular selectivities, and diffracted beam profiles. Volume gratings in both reflection and transmission geometries are investigated near 1550 nm. Numerical simulations utilizing the technique of Fourier decomposition provide a satisfactory explanation and confirm that the spread of spatial harmonics is the main contributing factor.
