title: PDMS embedded opto-fluidic microring resonator lasers.
abstract: Opto-fluidic ring resonator (OFRR) dye lasers are embedded in low index polydimethylsiloxane (PDMS) to achieve enhanced portability, mechanical stability, and potential integration with conventional soft lithography based microfluidics for development of micro total analysis systems. The OFRR retains high Q-factors (> 10(6)) and exhibits low lasing threshold (<1 microJ/mm(2)). Fiber prisms and tapered optical fibers are used to directionally couple out the laser emission. At 2.2 microJ/mm(2) pump intensity, the laser output from the fiber prism is 80 nW, corresponding to 50% power extraction efficiency. A microarray structure of parallel OFRRs is also demonstrated, allowing simultaneous multi-color emissions.
