Effect of atomic position on the spontaneous emission of a three-level atom in a coherent photonic-band-gap reservoir

Photonic Crystals

“…It can be concluded that the constituent of the crystals and the geometry of the lattice are two key factors for the PBG. Thus, PhCs with PBGs could prevent light from propagating in certain directions with speci fi ed frequencies (Cheng et al 2009 ) . Nowadays, many methods for the numerical simulation of the electromagnetic fi eld propagation in PhCs have been developed, such as plane wave expansion (PWE) (Sakoda 2001 ) , fi nite-difference time-domain algorithm (FDTD) (Kosmidou et al 2005 ) , fi nite element method (FEM) (Fujisawa and Koshiba 2006 ) , and transfer-matrix method (TMM) (Pendry 1994 ) .…”

“…Research has shown that PhCs possess unique properties such as a photonic bandgap (PBG) (Cheng et al 2009 ) , photonic localization (Maloshtan and Kilin 2007 ) , slow light devices based on PhCs (Adachi et al 2010 ) , and so on (Zhao et al 2011 ) . It was established that the propagation of photons in PhCs is similar to the propagation of electrons in conducting crystals.…”

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

“…The phenomenon can originate from destructive quantum interference. The same atom system considering the effect of atomic position has been investigated, and the results show that the variation of the atomic position can lead to large shift of spectral peak [15]. The emission spectrum of a three-level V-type atom [16] has also been investigated, in which a spectral narrowing and a black line are induced by quantum interference.…”

Abnormal properties of spontaneous emission in a Kerr nonlinear blackbody

“…However, when an atom is located at some unusual electromagnetic environment instead of free space, the spontaneous emission can be modified. For example, the spontaneous emission can be enhanced or inhibited in a cavity [22][23][24][25][26][27] and it can also be modified in photonic crystals [13][14][15][16][17]20,21,[28][29][30][31][32][33][34] or in left-hand materials [18,19]. What is more, when an atom is embedded in a linear dielectric, the atomic spontaneous decay can also be modified [35][36][37][38][39].…”
