Two–color holographic recording scheme allowing nonvolatile reading in Mn: Yalo3
Abstract
We propose and experimentally realize the recording of two-color holographic gratings in Mn:YAlO3, a potential material for holographic data storage. This type of recording allows for nonvolatile retrieval of recorded information at the recording wavelength. We demonstrate two-color recording and readout of a 256 × 256 pixel page using red and green laser beams with a bit error rate of 6 × 1027. © 2001 Optical Society of America.
