    摘要: A three dimensional optical data storage and retrieval system that includes a three dimensional optical data storage medium and an apparatus for providing access to data stored on the medium. The data storage medium includes an optical data storage material which either a low molecular weight or polymeric glassy solid that are capable of undergoing multi-photon excitation that are energetically different in the write and read cycles. The optical data storage materials provide substantially higher storage capacities relative to conventional materials, and show high robustness in that written and stored data can undergo multiple read cycles without erasure or overwriting. An apparatus for data recording and accessing stored data on the medium includes a controllable variable energy photo-emitting excitation source and an emission photo-detector.

    摘要: An apparatus for generating a strong source of doubly or multiply entangled photons emitted non-collinearly or collinearly with respect to the pump light that is at frequency 2f includes a laser medium producing classical laser light at fundamental frequency f. A medium for second harmonic generation transforms the light at fundamental frequency f to its second-harmonic frequency 2f and emitting entangled photons non-colinearly with respect to the light at the second harmonic frequency. An optical cavity element around the laser medium and the medium for second harmonic generation includes of at least two mirrors that are highly reflective at the light frequencies f and 2f. A parametric process or a set of simultaneous parametric processes are used to generate the entangled photons at light frequencies around including at least one optical cavity resonant at frequency 2f at least around the medium for entangled photon generation, comprising of at least two mirrors that are highly reflective at the light frequency 2f.
