Blue-sensitive rewriteable holographic media

An easily fabricated organic holographic media is presented that is rewriteable, sensitive to 407-nm light, and that exhibits high storage capacity, photosensitivity, and environmental robustness. Data written in this media is nonvolatile to readout with the blue write beam, and is only erased by irradiation with UV light. Over 50 holographic write/erase cycles have been demonstrated to date.
