Population Oscillation in Two-band Photonic Crystals Via Quantum Interference

We investigate the spontaneous emission from a V three-level atom embedded in two-band photonic crystals. The dipoles of the two transitions from the two upper levels to the lower level are parallel. Due to the quantum interference between the two decay processes and the existence of two bands, the populations in the excited states display some novel properties, which strongly depend on the initial states and the relative position of the upper levels from forbidden gap.
