- Title: Nano-fluidic dye laser
- Authors: Morten Gersborg-Hansen, Anders Kristensen
- Abstract: This letter describes the design and operation of a single mode polymer-based nano-fluidic dye laser. The device relies on light-confinement in a nano-structured polymer film where an array of nano-fluidic channels is filled by capillary action with a liquid dye solution which has a refractive index lower than that of the polymer. In combination with a third order distributed feed-back (DFB) grating, formed by the array of nano-fluidic channels, this yields a low threshold for lasing. The laser is straight-forward to integrate on Lab-on-a-Chip micro-systems, e.g. for novel sensor concepts, where coherent, tunable light in the visible range is desired.
