摘要：
The authors present time-resolved studies of laser emission from an organic microcavity filled with a guest-host composite of tris(8-hydroxy quinoline) aluminium and 4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran. A line splitting of 0.18 THz between two perpendicularly polarized lines is observed, resulting from an optical anisotropy in the distributed Bragg reflectors. This particular behavior is attributed to oblique columnar structures shaped by off-axial preparatory conditions. By means of an upconversion setup an oscillation at 5.5 ps period time and phase coupling of the modes are observed. A rate-equation-based approach is utilized for modeling the temporal behavior.
