steady density
解釋
穩定密度-
Spontaneous emission can be totally suppressed or strongly enhanced depending on the relative position of the resonant frequency from the edge of the photonic band gap and the photonic mode density. several novel phenomena can be obtained. the spontaneous emission displays an oscillatory behavior, classical light localization, photon - atom bound state, nonzero steady - state population and anomalously large vacuum rabi splitting. and localized mode associated with a defect site in an otherwise perfect photonic crystals, acts as a high - q micro - cavity
