Abstract

Digital data-page holograms consisting of 1024×1024 arrays of binary pixels have been stored and subsequently retrieved with an optical exposure consistent with a data rate 1  Gbit/s. Each input pixel was precisely registered with a single detector pixel, and a raw bit-error rate as low as 2.4×10-6 was demonstrated with global-threshold detection. To our knowledge, this is the first demonstration of the often-cited goal of holographic data storage of megabit data pages and a gigabit-per-second data rate.

Histograms of (a) the megabit image and (b) the hologram. Fitting of the tails of the distributions of 0's (circles) and 1's (squares) to Gaussian yields the solid curves and an estimate of the BER of 3.4×10-6 for the image and 2.4×10-6 for the hologram.

Fig. 2
Fig. 2

Increase in the BER with repeated exposure for both xyz and 45° crystals. The dotted line shows the desired raw error rate 10-5. Errors increase more rapidly for the xyz-cut crystal orientation (squares). For the 45° crystal, the circles and diamonds show two 50-exposure runs with a reoptimization of the imaging of the tester in between.

Fig. 3
Fig. 3

Improvement in the BER is shown when blocked thresholding is used, with blocks as shown in the inset, compared with the BER with global thresholding. Squares, xyz-cut crystal; circles, 45° crystal.
