Paper Abstract

The gain/attenuation factor for lightwave propagating in 1D photonic band-gap (PBG) structure having layers with gain/losses was calculated using Kronig-Penny model. Special attention was given to the dispersion characteristics near the boundary of band gap. To distinguish between the directions of propagation, gain and attenuation the complex frequency of eigenwaves was used in the spirit of the theory of instabilities. It was shown the presence of bad gaps does not lead to considerable gain/loss enhancement and the gain is definitely absent within the band gaps. Possible mechanisms of gain enhancement were discussed.
