| Abstract: |
Theoretical analysis of threshold gain and absorption efficiency is presented for a vertical-cavity surface-emitting organic laser by using transfer matrix method. Pyrromethene 567 dye doped in a polymer film is examined for verification of the active material with an InGaN cyan LED as a pump source. By alternately stacking high- and low-refractive-index active polymer films, modeling results indicate that the threshold gain can be reduced and the absorption efficiency at the pump wavelength can be improved compared with those of a vertical cavity with a dielectric mirror stack. The absorption efficiency of the distributed-feedback resonator is not practically degraded even if the pump wavelength is located near the stopband. [ABSTRACT FROM AUTHOR] |
