摘要：
Tuning of distributed feedback lasing is demonstrated in a thin film of the conjugated polymer poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinylene). By using an array of different grating periods on a single substrate, the laser emission was systematically tuned from 612 to 632 nm The Bragg scattered emission from the film features a dip at the Bragg wavelength; lasing occurs at the long-wavelength edge of this stopband.
