  Quantum vortices in the color-flavor locked (CFL) phase of QCD have bosonic
degrees of freedom, called the orientational zero modes, localized on them. We
show that the orientational zero modes are electromagnetically charged. As a
result, a vortex in the CFL phase nontrivially interacts with photons. We show
that a lattice of vortices acts as a polarizer of photons with wavelengths
larger than some critical length.
