Recently, two-color photon-gated persistent spectral hole-burning (PHB) was observed for the first time in an inorganic material (BaClF:Sm2+) and an organic material (carbazole in boric acid glass). By demonstrating that nondestructive reading of spectral holes is possible, a new dimension for optical storage of information has been opened up.
