Abstract
Tuning of distributed feedback lasing is demonstrated in a thin film of the
conjugated polymer poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinyl
ene). 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 s
cattered emission from the film features a dip at the Bragg wavelength; las
ing occurs at the long-wavelength edge of this stopband.
