This letter describes the design and operation of a polymer-based third orderdistributed feed-back (DFB) microfluidic dye laser. The device relies onlight-confinement in a nano-structured polymer film where an array ofnanofluidic channels is filled by capillary action with a liquid dye solutionwhich has a refractive index lower than that of the polymer. In combinationwith a third order DFB grating, formed by the array of nanofluidic channels,this yields a low threshold for lasing. The laser is straight-forward tointegrate on Lab-on-a-Chip micro-systems where coherent, tunable light in thevisible range is desired.Comment: 4 pages, 3 figure
