✦ Synopsis

We introduce a modified density of modes to investigate the spontaneous emission spectrum of a threelevel V-type atom in photonic crystal using Laplace transform. The atom's steady state behavior of spontaneous emission is treated for different locations of the upper band-edge frequency. Furthermore; the influence of quantum interference between the two decay channels on spontaneous emission is discussed.

The spontaneous emission properties of a K type atom embedded in a three-dimensional anisotropic photonic crystal are investigated. Only one of the two atomic transition frequencies is considered near the photonic band edge. The atomic decay properties such as the time-evolution of the excited-state
