Abstract

Summary form only given. Optically pumped lasing from polymeric gain media has been a subject of intense research efforts with a view to the realization of electrically pumped polymer lasers. The recent achievement of solid-state injection laser with an organic crystal has provided incentive to pursue the electrically pumped polymer lasers. We fabricated step index polymer fibers using conjugated polymers and fluorescent compound-doped polymers as gain media and observed amplified spontaneous emission from the fibers when they were optically pumped. Construction of such waveguiding structure offers the reduction of the lasing threshold, required to realize efficient optically pumped polymer lasers as well as electrically pumped polymer lasers.
