Abstract / Description of output

This paper aims to give an overview of distributed feedback (DFB) lasing in chiral nematic liquid crystals (CLC) and explain the salient features that render them unique. Particular emphasis is given to the transmission and reflection characteristics of CLCs as well as to the key role of the Density of Photon States (DOS) in the presence of an active medium. Discussions and comparisons with wave propagation in other periodic solid media are also included.
