摘要：

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 multiple-band electrotunable filters. Using the latter dye-doped hybrid film red green blue simultaneous lasing due to Fabry Perot cavity modes is achieved (see figure).
