Recording data using a femtosecond-laser was first proposed and demonstrated in 1996. [1] [14] [15] The storage medium consists of fused quartz, where the spatial dimensions, intensity, polarization, and wavelength are used to modulate data. By introducing gold or silver nanoparticles embedded in the material, their plasmonic properties can be ...
