  • Method and apparatus providing 2-D/3-D optical information storage and retrieval in transparent materials
    Patent number: 5761111
    Abstract: Sub-micron-scale, micron-scale and greater than micron-scale, crack-free and regularly-shaped structures of high-contrast refractive index are provided in transparent storage media by controllably focusing ultrashort laser pulses in the bulk of virtually any transparent medium respectively during operation in a "low energy," a "high energy", and a "third" operating regime. In any operating regime, the crack-free and regularly-shaped structures of high-contrast refractive index may be controllably patterned in 2-D or 3-D so as to permanently store both digital and non-digital information in the bulk of the transparent storage medium. For digital-type information, greater than one (1) Terabit, and up to one hundred (100) Terabit, digital information storage capacity in a CD-ROM sized disc is provided.
