Modified spontaneous emission spectra of a three-level V-type atom in photonic crystals

Spontaneous emission with a cascaded driving field in the same transition channel

“…The spontaneous emission can be significantly suppressed or enhanced for excited atoms in cavities. Since an effective high-Q cavity [6] can be obtained by using photonic band gap material [7][8][9][10][11][12], the spontaneous emission near the edge of a photonic-band-gap has attracted substantial attention in the literature [13][14][15][16].…”

Modification of spontaneous emission from a five-level M-type atom in coupled cavity waveguide

“…This property excellently mimics the counterpart for an electron-impurity level bound state in the gap a semiconductor. Because the density of modes of photonic-band-gap reservoir is significantly different from that of empty space, placing the atom in photonic band gap material [6][7][8][9][10][11][12][13][14] to control spontaneous emission has attracted intensive attention. For a three-level -type atom, when one transition is coupled by Markovian reservoir and the other is coupled by non-Markovian reservoir, there will be dark lines existing in the spontaneous emission spectrum [8].…”

Calculation of spontaneous emission from a V-type three-level atom in photonic crystals using fractional calculus

“…The study of V-type atom systems embedded in PCs was focused mainly on their emission spectra [22,28,29], but rarely on the evolution of the excited-state population due to the requirement for dealing with complex integration in the inverse Laplace transformation [21,30]. In order to simplify the computation, the band-edge frequency of the PC was usually assumed midway between two excited levels of the V-type atom [31] in the isotropic models [30].…”
