Abstract

Whispering Gallery Mode (WGM) emission has been observed from Ag nanowire doped polymer optical fiber laser. Low threshold lasing and high photostability of the active medium has been noticed with a given concentration of Ag nanowires in the microcavity of the fiber. Quantumyield andlifetimemeasurements of thedye (activemedium) withand withoutnanowires confirm thatpresenceofnanowires enhance the rateof radiative decayof thefluorophore, therebyproviding lowpumppulse energy for the excitation of lasing modes in the cavity, as compared with a bare dye-doped polymer fiber laser.
