Abstract
Digital storage, compared to paper or stone, is not very durable. The main problem is the lack of suitable storage technology and media that has the advantages of both high capacity and long life. Recently, ultrafast laser writing through anisotropic nanostructures in silica glass for optical memory with high-capacity polarization multiplexing has been proposed and demonstrated. The storage provides hundreds of terabytes of data capacity, thermal stability up to thousand degrees thousand degrees Celsius, and virtually unlimited room temperature life, recognized by the Guinness Book of Records as the most durable digital storage medium. The successful demonstration of writing and reading data in a 5D memory crystal opens an opportunity to challenge the traditional design of cloud storage systems and ultimately achieve information immortality.
Biography
Peter G. Kazansky studied physics in Moscow State University and received Ph.D. from the General Physics Institute in 1985. From 1989 to 1993 he led a group in the GPI, which unraveled the mystery of light-induced frequency doubling in glass. In 1992 he joined the ORC at the University of Southampton where since 2001 he is a professor pursuing his interests in new optical materials and phenomena. More recently he pioneered the field of ultrafast laser nanostructuring in glass leading to invention of “5D memory crystal,” which holds a Guinness world record for the most durable data storage medium. He is a Fellow of the Optical Society of America.
