摘要：
Microring cavities were fabricated by depositing poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinylene) (MEH-PPV) on glass fibers by a dip-coating method. Laser emissions in whispering gallery modes were observed by pumping with a frequency-doubled Nd:YAG laser. The threshold energy of the MEH-PPV microring laser was as low as 10 nJ per pulse (1.5 mu J/mm(2)). The polarization characteristics of the microring lasers were studied and a polarization model was developed to explain the observed phenomena.
