✦ Synopsis

Two-polariton spontaneous emission is studied in dispersive and photonic band-gap materials doped with a three-level atom in the cascade conÿguration. It is found that when the two resonance frequencies of the top and middle excited states of the atom lie outside the band gap, an emission of two polaritons can cause an interference e ect. If on the other hand, the resonance frequency of the top state lies within the band gap and the resonance frequency of the middle state lies either within the band gap or outside the band gap, emission of both polaritons is forbidden and no interference e ect should be observed.

## Abstract This paper shows that inside photonic band gap (PBG) materials the effective index of refraction __n__~__eff__~, defined in terms of group velocity, becomes negative in a certain range of frequencies. Also, near the photonic‐band edge the effective index of refraction __n__~__eff__~ att

## Abstract In the paper of Ojha et al. (Microwave Opt Technol Lett 42 (2004), 82–87), an erroneous definition of the effective refractive index __n__~__eff__~ in a photonic band gap (PBG) structure is used. The effective refractive index __n__~__eff__~ is defined as a function of the group velocit
