Optical data storage by electromagnetically induced transparency and nondegenerate four-wave mixing in a spectral hole-burning solid

摘要

Summary form only given. We demonstrated two bits of optical data storage by a novel technique of electromagnetically induced transparency (EIT)-excited spin echoes. This experiment demonstrates the potential of high-density and fast optical data memory at high temperature. We show its first application to optical data storage using spin photon echo excited by two-photon resonance.
