FIGURE 1. Depiction of the ultrahigh-density optical memory. Red dots represent rare earth ion impurities, and blue dots represent defects onto which the excitation is stored by using near-field energy transfer processes. Many optically addressable RE ions within the diffraction-limited excitation volume (red beam) result in an enhanced bit density.
