Photopumped pulsed lasing in the green spectral range is reported for cylindrical microcavities in which the active layers are films of disubstituted polyacetylene derivatives. The various cavity-dependent laser modes observed in both micro-rings coated around thin optical fibers and microdisks deposited on flat quartz substrates are described. In addition the feasibility of fabricating high Q cylindrical light-emitting diodes (LEDs) from flat polymer microdisks is demonstrated—an important step towards the realization of electrically pumped, green-emitting, plastic laser diodes using cylindrical microcavities.
