Optical 3D-storage in sol-gel materials with a reading by optical coherence tomography-technique
Abstract
We report on the recording of 3D optical memories in sol-gel materials by using a non-linear absorption effect. This effect induces a local change in optical properties of the material which is read and quantified with a high-resolution full-field optical coherence tomography setup. It is the first time that this technique is used for this purpose. Data recording was performed by focused picosecond (ps) single-pulse irradiation at 1064 nm with energy densities of 10 and 33 J/cm2 per pulse.
