A three-level atomic system in V-configuration (interacting with a single mode laser field) with parallel transition dipole moments exhibiting spontaneously generated coherence due to quantum interference of decaying channels is considered here for the purpose of storing light pulses. This system is equivalent to (with some restrictions) another three-level system in which ground state is coupled with one of the upper states but the upper states are coupled through a DC field and hence can be used to store electromagnetic pulse using the concept of dark-state-polariton.
