Microlasers and Micro-LEDs from Disubstituted Polyacetylene

Abstract

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.
