Fabrication of Flexible Distributed Feedback Laser Using Photoinduced Surface Relief Grating on Azo-Polymer Film as a Template

An all-polymer flexible distributed feedback (DFB) laser has been fabricated using a photoinduced surface relief grating (SRG) on an azo-polymer film as a template. The holographically induced SRG on the azo-polymer was transferred onto a flexible film of a UV-curable photopolymer. Optically pumped mirrorless DFB laser action was observed from a conducting polymer, poly(2-methoxy-5-dodecyloxy- p -phenylenevinylene) (MDDO-PPV), spin-coated on the transferred SRG.
