In this paper, a thiol-ene based polymer waveguide, defined by UV-assisted soft lithography, is designed, fabricated and
characterized. Waveguides are formed by filling microfluidic channels with a high refractive index liquid mixture of ‘thiol’
and ‘ene’ monomers (e.g., trimethylolpropane tris(3-mercaptopropionate) = ‘thiol’, and
1,3,5-triallyl-1,3,5-triazine-2,4,6(1H,3H,5H)-trione = ‘ene’), which can be cured by UV exposure into a solid polymer. The
waveguides demonstrated good confinement of light, and a propagation loss of 0.5 dB/cm was obtained. To our best
knowledge, this is the first report to employ thiol-ene based polymers as waveguide core materials for potential optofluidic
applications.
