Abstract :
Lasing from a conjugated polymer, poly(9,9-di-(2-ethylhexyl)fluorenyl-2,7´-diyl), incorporated into a glass-clad step index optical fibre structure is reported. The fibre is fabricated by filling a glass capillary with a toluene solution containing polystyrene and the conjugated polymer. Under nanosecond transverse photopumping, the fibre 1.5 cm in length exhibits laser emission at 436 nm from a Fabry-Perot cavity formed by the Fresnel reflections at the fibre end-air interfaces
