摘要：
Multiple bits of information have been stored in the frequency domain in bulk glass using optically encoded chi(2) gratings. The information is read out by measuring second harmonic generation from the encoded glass as a function of wavelength. Information densities in excess of 10(8) bits/cm2 should be possible using this effect. The storage is stable under readout conditions, and the information can be erased and rewritten.
