We study the conductivity of a strongly coupled striped superconductor using
gauge/gravity duality (holography). The study is done analytically, in the
large modulation regime. We show that the optical conductivity is inhomogeneous
but isotropic at low temperatures. Near but below the critical temperature, we
calculate the conductivity analytically at small frequency \omega, and find it
to be both inhomogeneous and anisotropic. The anisotropy is imaginary and
scales like 1/\omega. We also calculate analytically the speed of the second
sound and the thermodynamic susceptibility.Comment: 32 page
