Room temperature nanoimprinting lithography is used to realize a distributed feedback laser by direct dry pressing of the conjugated polymer (poly_2-methoxy-5-_2-ethylhexyloxy_-1,4- phenylenevinylene). The laser device exhibits emission at 630 nm with a pump threshold of 25 microJ/cm2 and a polarization contrast of the emitted light as large as 0.91. Therefore, room temperature nanoimprint lithography turns out to be very effective for producing stable patterns on light-emitting polymers for the one-step fabrication of nanopatterned optoelectronic devices.

Abstract
Room temperature nanoimprinting lithography is used to realize a distributed feedback laser by direct dry pressing of the conjugated polymer (poly_2-methoxy-5-_2-ethylhexyloxy_-1,4- phenylenevinylene). The laser device exhibits emission at 630 nm with a pump threshold of 25 microJ/cm2 and a polarization contrast of the emitted light as large as 0.91. Therefore, room temperature nanoimprint lithography turns out to be very effective for producing stable patterns on light-emitting polymers for the one-step fabrication of nanopatterned optoelectronic devices.File in questo prodotto:
