Discovering New Phenomena and Applications with Ultrafast Laser Writing in Glass
Demonstrations of self-assembled sub-wavelength structuring and related form birefringence have uncovered new science and applications including flat optics elements exploiting geometrical phase. The S-waveplate is one of such elements, which can be used for polarization and phase shaping with application ranging from material processing and optical trapping to extreme ultraviolet vector beam generation. The two independent parameters describing self-assembled form birefringence in quartz glass, the slow axis orientation (4 th dimension) and the strength of retardance (5 th dimension), were also explored for the optical encoding of information in addition to three spatial coordinates. The data optically encoded into five dimensions was successfully retrieved by quantitative birefringence measurements. The storage allows unprecedented parameters including hundreds of terabytes per disc data capacity and thermal stability up to 1000°. The recording of the first digital documents in 5D memory crystal including the eternal copy of Newtons Opticks is a vital step towards an eternal archive insuring the preservation of mankind memory. These and other demonstrations challenging common beliefs in optics including ultrafast laser calligraphy and anisotropic writing in transparent materials will be reviewed.
Speaker: Professor Peter G. Kazansky studied physics in Moscow State University and received his PhD under the supervision of Nobel Laureate, for the invention of laser, A.M. Prokhorov. Professor Kazansky is leading the physical optics group in the Optoelectronics Research Centre at the University of Southampton pursuing his interests in new materials and ground-breaking optical phenomena. He discovered the fundamental constituent of the concept of 5D optical memory, which exhibits unprecedented durability and practically unlimited lifetime

He is a celebrated scientific author who has won many awards for his outstanding and imaginative scientific contributions, and is a Fellow of the Optical Society of America. Professor Kazansky is an advisor for the Arch Mission Foundation (https://archmission.org/), a non-profit corporation designed to continuously preserve and disseminate humanity’s most important knowledge across time and space.
