Experimental high density optical memory using the dichroic absorption of the m(a) color center.
An experimental, high density optical memory using M(A) color centers in KCI has been built to study the application of color centers as read, write, and erase computer bulk memories. M(A) centers are employed as a binary indicator by making use of their ability to reorient in the KCI lattice when excited with either [110] or [110] polarized 531-nm light. Information is read out with circularly polarized 531-nm light. Results indicate that writing times of less than 5 microsec and packing densities exceeding 10(6) bits/cm(2) will be possible in a fully developed system.
