Query: Observation of the gradual transition from one-dimensional to
  two-dimensional Anderson localization   We study the gradual transition from one-dimensional to two-dimensional
Anderson localization upon transformation of the dimensionality of disordered
waveguide arrays. An effective transition from one- to two-dimensional system
is achieved by increasing the number of rows forming the arrays. We observe
that, for a given disorder level, Anderson localization becomes weaker with
increasing number of rows, hence the effective dimension.
