DIPOLE EMISSION RATES IN ONE-DIMENSIONAL PHOTONIC BAND-GAP MATERIALS

We numerically investigate dipole emission rates in one-dimensional ph otonic band-gap structures. Both the temporal and spatial dynamics of the electromagnetic field and the atomic polarization are treated by a unique propagation method that allows us to easily and realistically model material boundary conditions for finite structures. We find that for our structure the total power emitted is enhanced near the photon ic band edge by more than an order of magnitude, and that this power i s drastically reduced by nearly three orders of magnitude when the dip ole oscillation frequency is tuned near the center of the forbidden ph otonic band gap.
