Abstract

We report on an original design and fabrication of microfluidic dye laser integrated into a functional poly-dimethylsiloxane (PDMS) lab-on-a-chip system. Soft lithography has been used for the fabrication of the microfluidic channels allowing the liquid dye circulation. The laser cavity, formed by two cleaved optical fibers with end face metallization, is directly integrated into a microfluidic channel. The active dye molecules are optically pumped by a pulsed and frequency-doubled Nd:Yag laser at 532 nm wavelength. Finally, the output laser beam is extracted and coupled into the optical fiber. As a result, the characteristics of the laser output power as a function of pumping energy density is presented. We also show that the micro dye laser we fabricated can work steadily with an average output power up to 0.35 mW. The wavelength tunability is also demonstrated with the laser system.
