Multiple storage holograms in Bi12SiO20 with dual-wavelength recording and readout

Abstract

Multiple holograms in a PRC using angle-multiplexing have been reported. These experiments, however, used a different PRC and did not include a dual-wavelength approach. In this paper, two plane wave holograms are recorded simultaneously in a bismuth silicon oxide crystal (Bi₁₂SiO₂₀) by angle-multiplexing. The grating lifetime is then extended by a dual-wavelength scheme.
