assembled nanogratings produced by ultrafast laser writing in
glass were proposed for the polarization multiplexed optical memory,
where the information encodi
ng would
be realized by means of two birefringence parameters, i.e. the slow axis orientation (4th dimension) and
strength of retardance (5th dimension), in addition to three spatial coordinates

The five dimensions are in the first paragraph:
