"holography reached saturation using light's wavelength, polarization, orbital angular momentum encoding data... overcome using optical orbital angular momentum multiplication operator-specific holograms requiring specific mathematical pathways to open... each operator defined by: incident topological charge, scaling factor, propagation distance... 9X increased optical data storage capacity subdividing single channel, etching multiplexed independent holograms into glass using fs lasers"
