  Resonant metamaterials usually exhibit substantial dispersion, which is
considered a shortcoming for many applications. Here we take advantage of the
ability to tailor the dispersive response of a metamaterial introducing a new
method of group-velocity dispersion compensation in telecommunication systems.
The method consists of stacking a number of highly dispersive sheet
metamaterials and is capable of compensating the dispersion of optical fibers
with either negative or positive group-velocity dispersion coefficients. We
demonstrate that the phase-engineered metamaterial can provide strong
group-velocity dispersion management without being adversely affected by large
transmission loss, while at the same time offering high customizability and
small footprint.
