概要
- 論文の詳細を見る
We fabricated a hybrid structure composed of a dye-doped low-molecular-weight cholesteric liquid crystal (low CLC) sandwiched between polymer cholesteric liquid crystal (PCLC) films with the same handedness as the low CLC, and studied its lasing characteristics. Defect-mode lasing was observed with a threshold reduced by a factor of 3 compared with that in a simple dye-doped low CLC cell. Experimental and simulated results for the transmittance, emission, and photonic density-of-states spectra are also discussed.
