Abstract
Multiple polymer cholesteric liquid crystal (PCLC) layers with different pitches and a sandwich structure of nematic liquid crystal by these PCLC films are presented. The former serves as broadband-distributed Bragg reflectors and the latter as multipleband electrotunable filters. Using the latter dye-doped hybrid film red-green-blue simultaneous lasing due to Fabry-Perot cavity modes is achieved (see figure). (Figure Presented) © 2010 WILEY-VCH Verlag GmbH & Co. KGaA,.
