  We propose a set of subradiant states which can be prepared and detected in a
one-dimensional optical lattice. We find that the decay rates are highly
dependent on the spatial phases imprinted on the atomic chain, which gives
systematic investigations of the subradiance in the fluorescence experiments.
The time evolution of these states can have long decay time where up to hundred
milliseconds of lifetime is predicted for one hundred atoms. They can also show
decayed Rabi-like oscillations with a beating frequency determined by the
difference of cooperative Lamb shift in the subspace. Experimental requirements
are also discussed for practical implementation of the subradiant states. Our
proposal provides a novel scheme for quantum storage of photons in arrays of
two-level atoms through the preparation and detection of subradiant states,
which offer opportunities for quantum many-body state preparation and quantum
information processing in optical lattices.
