Paper Abstract
Optically pumped surface emitting and edge emitting stimulated emission behaviors in organic semiconductors was demonstrated in this study. For the surface emitting device, the microcavity was formed by sandwiching a polymer film containing PVK, Alq and DCM between a DBR with a reflectivity of 99.5 percent and a silver film. The sample was optically pumped by the three harmonic of a observed in DCM-doped PVK microcavity when pumped above the threshold intensity of 0.25MW/cm2. The full width at half maximum was 0.6 nm with the peak wavelength at 603nm. For the edge emitting device, a laser dye DCM doped Alq matrix wa used as the gain medium. The sample was transversely pumped by the three harmonic output of the mode-locked Nd:YAG laser. The change of the emission spectra showed a clear threshold action and gain narrowing phenomenon when increasing the excitation intensity. The spectra narrowing observe result from the amplified spontaneous emission in the gain material.
