ABSTRACT:
A method for the optical writing of information elements uses a material (Ma) that is highly non-linear optically, on which it is possible to record information elements with sizes several times smaller than the writing wavelength. Also disclosed is a method for the reading of information elements recorded on a material (Ma) deposited on a material (Mb) capable of being the site of a stimulated emission generating the reading of the recorded information elements. Applications: high definition television, digital sound.
