Impact of phase aberrations caused by multilayer optical data storage in weakly inhomogeneous media

  title={Impact of phase aberrations caused by multilayer optical data storage in weakly inhomogeneous media},
  author={Robert R. McLeod},
Various multilayer optical data storage methods have been proposed in which bits are written in an initially homogeneous material. To varying degrees, all of these methods will be constrained by phase aberrations that decrease the Strehl ratio as the number of layers and index perturbation of each bit are increased. Although the exact problem is theoretically and numerically intractable, statistical derivations of the impact are possible. These analytic expressions are derived and validated… CONTINUE READING
