  We address the superconducting singlet state of anisotropic Dirac fermions
that disperse linearly in one direction and parabolically in the other. For
systems that have uniaxial anisotropy, we show that the electromagnetic
response to an external magnetic flux is extremely anisotropic near the quantum
critical point of the superconducting order. In the quantum critical regime and
above a critical magnetic field, we show that the superconductor may form a
novel exotic smectic state, with a stripe pattern of flux domains.
